283593-12-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 283593-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,3,5,9 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 283593-12:
(8*2)+(7*8)+(6*3)+(5*5)+(4*9)+(3*3)+(2*1)+(1*2)=164
164 % 10 = 4
So 283593-12-4 is a valid CAS Registry Number.
