Check Digit Verification of cas no
The CAS Registry Mumber 77918-45-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,1 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77918-45:
(7*7)+(6*7)+(5*9)+(4*1)+(3*8)+(2*4)+(1*5)=177
177 % 10 = 7
So 77918-45-7 is a valid CAS Registry Number.
