Check Digit Verification of cas no

The CAS Registry Mumber 347886-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,7,8,8 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 347886-63:
(8*3)+(7*4)+(6*7)+(5*8)+(4*8)+(3*6)+(2*6)+(1*3)=199
199 % 10 = 9
So 347886-63-9 is a valid CAS Registry Number.
