93646-66-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 93646-66-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,6,4 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 93646-66:
(7*9)+(6*3)+(5*6)+(4*4)+(3*6)+(2*6)+(1*6)=163
163 % 10 = 3
So 93646-66-3 is a valid CAS Registry Number.
