Check Digit Verification of cas no
The CAS Registry Mumber 12778-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,7,7 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12778-65:
(7*1)+(6*2)+(5*7)+(4*7)+(3*8)+(2*6)+(1*5)=123
123 % 10 = 3
So 12778-65-3 is a valid CAS Registry Number.
