Check Digit Verification of cas no
The CAS Registry Mumber 16921-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,2 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16921-91:
(7*1)+(6*6)+(5*9)+(4*2)+(3*1)+(2*9)+(1*1)=118
118 % 10 = 8
So 16921-91-8 is a valid CAS Registry Number.
