Check Digit Verification of cas no

The CAS Registry Mumber 851853-42-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,8,5 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 851853-42:
(8*8)+(7*5)+(6*1)+(5*8)+(4*5)+(3*3)+(2*4)+(1*2)=184
184 % 10 = 4
So 851853-42-4 is a valid CAS Registry Number.
