Check Digit Verification of cas no
The CAS Registry Mumber 6473-34-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,7 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6473-34:
(6*6)+(5*4)+(4*7)+(3*3)+(2*3)+(1*4)=103
103 % 10 = 3
So 6473-34-3 is a valid CAS Registry Number.
