Check Digit Verification of cas no
The CAS Registry Mumber 87172-77-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,1,7 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87172-77:
(7*8)+(6*7)+(5*1)+(4*7)+(3*2)+(2*7)+(1*7)=158
158 % 10 = 8
So 87172-77-8 is a valid CAS Registry Number.
