Check Digit Verification of cas no

The CAS Registry Mumber 1067892-82-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,7,8,9 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1067892-82:
(9*1)+(8*0)+(7*6)+(6*7)+(5*8)+(4*9)+(3*2)+(2*8)+(1*2)=193
193 % 10 = 3
So 1067892-82-3 is a valid CAS Registry Number.
