Check Digit Verification of cas no

The CAS Registry Mumber 193892-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,8,9 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 193892-85:
(8*1)+(7*9)+(6*3)+(5*8)+(4*9)+(3*2)+(2*8)+(1*5)=192
192 % 10 = 2
So 193892-85-2 is a valid CAS Registry Number.
