Check Digit Verification of cas no
The CAS Registry Mumber 91999-87-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,9 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.Calculate Digit Verification of CAS Registry Number 91999-87:
(7*9)+(6*1)+(5*9)+(4*9)+(3*9)+(2*8)+(1*7)=200
200 % 10 = 0
So 91999-87-0 is a valid CAS Registry Number.
