Check Digit Verification of cas no
The CAS Registry Mumber 88917-11-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,9,1 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 88917-11:
(7*8)+(6*8)+(5*9)+(4*1)+(3*7)+(2*1)+(1*1)=177
177 % 10 = 7
So 88917-11-7 is a valid CAS Registry Number.
