Uses

Different sources of media describe the Uses of 5210-25-3 differently. You can refer to the following data:
1. Used in the preparation of 7α-alkyl steroids.
2. 3-Methoxy-7α-Methyl-estra-2,5(10)-dien-17-one is used in the preparation of 7α-alkyl steroids.

Check Digit Verification of cas no

The CAS Registry Mumber 5210-25-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5210-25:
(6*5)+(5*2)+(4*1)+(3*0)+(2*2)+(1*5)=53
53 % 10 = 3
So 5210-25-3 is a valid CAS Registry Number.
