Check Digit Verification of cas no
The CAS Registry Mumber 197160-61-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,1,6 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 197160-61:
(8*1)+(7*9)+(6*7)+(5*1)+(4*6)+(3*0)+(2*6)+(1*1)=155
155 % 10 = 5
So 197160-61-5 is a valid CAS Registry Number.
