Check Digit Verification of cas no

The CAS Registry Mumber 137909-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,9,0 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 137909-92:
(8*1)+(7*3)+(6*7)+(5*9)+(4*0)+(3*9)+(2*9)+(1*2)=163
163 % 10 = 3
So 137909-92-3 is a valid CAS Registry Number.
