1089331-13-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1089331-13-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,9,3,3 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1089331-13:
(9*1)+(8*0)+(7*8)+(6*9)+(5*3)+(4*3)+(3*1)+(2*1)+(1*3)=154
154 % 10 = 4
So 1089331-13-4 is a valid CAS Registry Number.
