Check Digit Verification of cas no
The CAS Registry Mumber 81-65-2 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81-65:
(4*8)+(3*1)+(2*6)+(1*5)=52
52 % 10 = 2
So 81-65-2 is a valid CAS Registry Number.
