Check Digit Verification of cas no

The CAS Registry Mumber 199483-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,4,8 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 199483-29:
(8*1)+(7*9)+(6*9)+(5*4)+(4*8)+(3*3)+(2*2)+(1*9)=199
199 % 10 = 9
So 199483-29-9 is a valid CAS Registry Number.
