Check Digit Verification of cas no

The CAS Registry Mumber 141973-65-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,7 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 141973-65:
(8*1)+(7*4)+(6*1)+(5*9)+(4*7)+(3*3)+(2*6)+(1*5)=141
141 % 10 = 1
So 141973-65-1 is a valid CAS Registry Number.
