Check Digit Verification of cas no
The CAS Registry Mumber 197960-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,9,6 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 197960-31:
(8*1)+(7*9)+(6*7)+(5*9)+(4*6)+(3*0)+(2*3)+(1*1)=189
189 % 10 = 9
So 197960-31-9 is a valid CAS Registry Number.
