89936-31-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89936-31-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,3 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89936-31:
(7*8)+(6*9)+(5*9)+(4*3)+(3*6)+(2*3)+(1*1)=192
192 % 10 = 2
So 89936-31-2 is a valid CAS Registry Number.
