129-23-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 129-23-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129-23:
(5*1)+(4*2)+(3*9)+(2*2)+(1*3)=47
47 % 10 = 7
So 129-23-7 is a valid CAS Registry Number.
