Check Digit Verification of cas no
The CAS Registry Mumber 19116-81-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,1,1 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.Calculate Digit Verification of CAS Registry Number 19116-81:
(7*1)+(6*9)+(5*1)+(4*1)+(3*6)+(2*8)+(1*1)=105
105 % 10 = 5
So 19116-81-5 is a valid CAS Registry Number.
