Check Digit Verification of cas no
The CAS Registry Mumber 6373-76-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,7 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6373-76:
(6*6)+(5*3)+(4*7)+(3*3)+(2*7)+(1*6)=108
108 % 10 = 8
So 6373-76-8 is a valid CAS Registry Number.
