Check Digit Verification of cas no

The CAS Registry Mumber 155104-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,1,0 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 155104-20:
(8*1)+(7*5)+(6*5)+(5*1)+(4*0)+(3*4)+(2*2)+(1*0)=94
94 % 10 = 4
So 155104-20-4 is a valid CAS Registry Number.
