31934-89-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31934-89-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,9,3 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 31934-89:
(7*3)+(6*1)+(5*9)+(4*3)+(3*4)+(2*8)+(1*9)=121
121 % 10 = 1
So 31934-89-1 is a valid CAS Registry Number.
