Check Digit Verification of cas no
The CAS Registry Mumber 1313-83-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,1 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1313-83:
(6*1)+(5*3)+(4*1)+(3*3)+(2*8)+(1*3)=53
53 % 10 = 3
So 1313-83-3 is a valid CAS Registry Number.
