871117-41-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871117-41-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,1,1 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 871117-41:
(8*8)+(7*7)+(6*1)+(5*1)+(4*1)+(3*7)+(2*4)+(1*1)=158
158 % 10 = 8
So 871117-41-8 is a valid CAS Registry Number.
