91167-83-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91167-83-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,6 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91167-83:
(7*9)+(6*1)+(5*1)+(4*6)+(3*7)+(2*8)+(1*3)=138
138 % 10 = 8
So 91167-83-8 is a valid CAS Registry Number.
