Check Digit Verification of cas no

The CAS Registry Mumber 856000-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,0,0 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 856000-41:
(8*8)+(7*5)+(6*6)+(5*0)+(4*0)+(3*0)+(2*4)+(1*1)=144
144 % 10 = 4
So 856000-41-4 is a valid CAS Registry Number.
