Check Digit Verification of cas no
The CAS Registry Mumber 79171-99-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,1,7 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 79171-99:
(7*7)+(6*9)+(5*1)+(4*7)+(3*1)+(2*9)+(1*9)=166
166 % 10 = 6
So 79171-99-6 is a valid CAS Registry Number.
