Check Digit Verification of cas no

The CAS Registry Mumber 209685-47-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,6,8 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 209685-47:
(8*2)+(7*0)+(6*9)+(5*6)+(4*8)+(3*5)+(2*4)+(1*7)=162
162 % 10 = 2
So 209685-47-2 is a valid CAS Registry Number.
