28646-14-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28646-14-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,4 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28646-14:
(7*2)+(6*8)+(5*6)+(4*4)+(3*6)+(2*1)+(1*4)=132
132 % 10 = 2
So 28646-14-2 is a valid CAS Registry Number.
