Check Digit Verification of cas no
The CAS Registry Mumber 5422-17-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,2 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5422-17:
(6*5)+(5*4)+(4*2)+(3*2)+(2*1)+(1*7)=73
73 % 10 = 3
So 5422-17-3 is a valid CAS Registry Number.
