Check Digit Verification of cas no

The CAS Registry Mumber 862015-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,0,1 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 862015-15:
(8*8)+(7*6)+(6*2)+(5*0)+(4*1)+(3*5)+(2*1)+(1*5)=144
144 % 10 = 4
So 862015-15-4 is a valid CAS Registry Number.
