Check Digit Verification of cas no
The CAS Registry Mumber 99135-95-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,3 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99135-95:
(7*9)+(6*9)+(5*1)+(4*3)+(3*5)+(2*9)+(1*5)=172
172 % 10 = 2
So 99135-95-2 is a valid CAS Registry Number.
