Check Digit Verification of cas no
The CAS Registry Mumber 91165-16-1 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 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91165-16:
(7*9)+(6*1)+(5*1)+(4*6)+(3*5)+(2*1)+(1*6)=121
121 % 10 = 1
So 91165-16-1 is a valid CAS Registry Number.
