Check Digit Verification of cas no

The CAS Registry Mumber 131923-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,2 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131923-99:
(8*1)+(7*3)+(6*1)+(5*9)+(4*2)+(3*3)+(2*9)+(1*9)=124
124 % 10 = 4
So 131923-99-4 is a valid CAS Registry Number.
