Check Digit Verification of cas no

The CAS Registry Mumber 649756-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,7,5 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 649756-22:
(8*6)+(7*4)+(6*9)+(5*7)+(4*5)+(3*6)+(2*2)+(1*2)=209
209 % 10 = 9
So 649756-22-9 is a valid CAS Registry Number.
