89940-12-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89940-12-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,4 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89940-12:
(7*8)+(6*9)+(5*9)+(4*4)+(3*0)+(2*1)+(1*2)=175
175 % 10 = 5
So 89940-12-5 is a valid CAS Registry Number.
