657-81-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 657-81-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 657-81:
(5*6)+(4*5)+(3*7)+(2*8)+(1*1)=88
88 % 10 = 8
So 657-81-8 is a valid CAS Registry Number.
