Check Digit Verification of cas no
The CAS Registry Mumber 77411-88-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,1 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77411-88:
(7*7)+(6*7)+(5*4)+(4*1)+(3*1)+(2*8)+(1*8)=142
142 % 10 = 2
So 77411-88-2 is a valid CAS Registry Number.
