4-5Check Digit Verification of cas no
The CAS Registry Mumber 6471-44-9 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 1 respectively; the second part has 2 digits, 4 and 4 respectively.Calculate Digit Verification of CAS Registry Number 6471-44:
(6*6)+(5*4)+(4*7)+(3*1)+(2*4)+(1*4)=99
99 % 10 = 9
So 6471-44-9 is a valid CAS Registry Number.
