Check Digit Verification of cas no

The CAS Registry Mumber 135809-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,8,0 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 135809-98:
(8*1)+(7*3)+(6*5)+(5*8)+(4*0)+(3*9)+(2*9)+(1*8)=152
152 % 10 = 2
So 135809-98-2 is a valid CAS Registry Number.
