64661-18-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64661-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,6,6 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 64661-18:
(7*6)+(6*4)+(5*6)+(4*6)+(3*1)+(2*1)+(1*8)=133
133 % 10 = 3
So 64661-18-3 is a valid CAS Registry Number.
