Check Digit Verification of cas no
The CAS Registry Mumber 667-96-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.Calculate Digit Verification of CAS Registry Number 667-96:
(5*6)+(4*6)+(3*7)+(2*9)+(1*6)=99
99 % 10 = 9
So 667-96-9 is a valid CAS Registry Number.
