Check Digit Verification of cas no
The CAS Registry Mumber 712-74-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,1 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 712-74:
(5*7)+(4*1)+(3*2)+(2*7)+(1*4)=63
63 % 10 = 3
So 712-74-3 is a valid CAS Registry Number.
