Check Digit Verification of cas no
The CAS Registry Mumber 871584-18-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,5,8 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 871584-18:
(8*8)+(7*7)+(6*1)+(5*5)+(4*8)+(3*4)+(2*1)+(1*8)=198
198 % 10 = 8
So 871584-18-8 is a valid CAS Registry Number.
