Check Digit Verification of cas no

The CAS Registry Mumber 1421767-20-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,7,6 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1421767-20:
(9*1)+(8*4)+(7*2)+(6*1)+(5*7)+(4*6)+(3*7)+(2*2)+(1*0)=145
145 % 10 = 5
So 1421767-20-5 is a valid CAS Registry Number.
