97218-71-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 97218-71-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,1 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 97218-71:
(7*9)+(6*7)+(5*2)+(4*1)+(3*8)+(2*7)+(1*1)=158
158 % 10 = 8
So 97218-71-8 is a valid CAS Registry Number.
