Check Digit Verification of cas no

The CAS Registry Mumber 144535-41-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,5,3 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144535-41:
(8*1)+(7*4)+(6*4)+(5*5)+(4*3)+(3*5)+(2*4)+(1*1)=121
121 % 10 = 1
So 144535-41-1 is a valid CAS Registry Number.
