Check Digit Verification of cas no
The CAS Registry Mumber 77411-83-7 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 3 respectively.
Calculate Digit Verification of CAS Registry Number 77411-83:
(7*7)+(6*7)+(5*4)+(4*1)+(3*1)+(2*8)+(1*3)=137
137 % 10 = 7
So 77411-83-7 is a valid CAS Registry Number.
