Check Digit Verification of cas no
The CAS Registry Mumber 16941-11-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,4 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16941-11:
(7*1)+(6*6)+(5*9)+(4*4)+(3*1)+(2*1)+(1*1)=110
110 % 10 = 0
So 16941-11-0 is a valid CAS Registry Number.
