2913-21-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2913-21-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,1 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2913-21:
(6*2)+(5*9)+(4*1)+(3*3)+(2*2)+(1*1)=75
75 % 10 = 5
So 2913-21-5 is a valid CAS Registry Number.
