Check Digit Verification of cas no

The CAS Registry Mumber 156022-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,0,2 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 156022-98:
(8*1)+(7*5)+(6*6)+(5*0)+(4*2)+(3*2)+(2*9)+(1*8)=119
119 % 10 = 9
So 156022-98-9 is a valid CAS Registry Number.
