Check Digit Verification of cas no
The CAS Registry Mumber 67411-81-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,1 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67411-81:
(7*6)+(6*7)+(5*4)+(4*1)+(3*1)+(2*8)+(1*1)=128
128 % 10 = 8
So 67411-81-8 is a valid CAS Registry Number.
