Check Digit Verification of cas no
The CAS Registry Mumber 6222-44-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,2 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6222-44:
(6*6)+(5*2)+(4*2)+(3*2)+(2*4)+(1*4)=72
72 % 10 = 2
So 6222-44-2 is a valid CAS Registry Number.
