Check Digit Verification of cas no

The CAS Registry Mumber 239795-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,9,7,9 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 239795-94:
(8*2)+(7*3)+(6*9)+(5*7)+(4*9)+(3*5)+(2*9)+(1*4)=199
199 % 10 = 9
So 239795-94-9 is a valid CAS Registry Number.
