Can someone out there tell me the DIN equivalent of Alloy 20 ( ASTM A744 CN7M )?

A713 & A771 which we pour both,

ASTM A 29 Standard Specification for Steel Bars, Carbon and Alloy, Hot-Wrought and Cold-Finished, General Requirements for lists the following grades that are close:
5115
C = 0.13-0.18
Si = 0.15-0.35
Mn = 0.70-0.90
Cr = 0.70-0.90
5120
C = 0.17-0.22
Si = 0.15-0.35
Mn = 0.70-0.90
Cr = 0.70-0.90
The DIN/EN grade 1.7139 has more Mn & Cr than either of these grades, so its hardenability will be higher than 5115. 5120 has slightly more carbon so it will be closer in hardenability, even with reduced Cr & Mn. Depending on your application, one of these grades or another alloy steel may be suitable.
Regarding equivalent steels & conversion among national & international standards, the following references are the best:
