Check Digit Verification of cas no
The CAS Registry Mumber 4735-65-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,3 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.Calculate Digit Verification of CAS Registry Number 4735-65:
(6*4)+(5*7)+(4*3)+(3*5)+(2*6)+(1*5)=103
103 % 10 = 3
So 4735-65-3 is a valid CAS Registry Number.
