Check Digit Verification of cas no

The CAS Registry Mumber 189079-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,7 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 189079-67:
(8*1)+(7*8)+(6*9)+(5*0)+(4*7)+(3*9)+(2*6)+(1*7)=192
192 % 10 = 2
So 189079-67-2 is a valid CAS Registry Number.
