Check Digit Verification of cas no
The CAS Registry Mumber 6411-51-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,1 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6411-51:
(6*6)+(5*4)+(4*1)+(3*1)+(2*5)+(1*1)=74
74 % 10 = 4
So 6411-51-4 is a valid CAS Registry Number.
