Check Digit Verification of cas no
The CAS Registry Mumber 19681-17-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,8 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19681-17:
(7*1)+(6*9)+(5*6)+(4*8)+(3*1)+(2*1)+(1*7)=135
135 % 10 = 5
So 19681-17-5 is a valid CAS Registry Number.
