Check Digit Verification of cas no

The CAS Registry Mumber 304875-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,4,8,7 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 304875-19:
(8*3)+(7*0)+(6*4)+(5*8)+(4*7)+(3*5)+(2*1)+(1*9)=142
142 % 10 = 2
So 304875-19-2 is a valid CAS Registry Number.
