Check Digit Verification of cas no

The CAS Registry Mumber 158977-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,9,7 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 158977-38:
(8*1)+(7*5)+(6*8)+(5*9)+(4*7)+(3*7)+(2*3)+(1*8)=199
199 % 10 = 9
So 158977-38-9 is a valid CAS Registry Number.
