Check Digit Verification of cas no

The CAS Registry Mumber 199340-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,3,4 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 199340-98:
(8*1)+(7*9)+(6*9)+(5*3)+(4*4)+(3*0)+(2*9)+(1*8)=182
182 % 10 = 2
So 199340-98-2 is a valid CAS Registry Number.
