Check Digit Verification of cas no

The CAS Registry Mumber 105997-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,9,9 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 105997-04:
(8*1)+(7*0)+(6*5)+(5*9)+(4*9)+(3*7)+(2*0)+(1*4)=144
144 % 10 = 4
So 105997-04-4 is a valid CAS Registry Number.
