Check Digit Verification of cas no

The CAS Registry Mumber 239104-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,9,1,0 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 239104-45:
(8*2)+(7*3)+(6*9)+(5*1)+(4*0)+(3*4)+(2*4)+(1*5)=121
121 % 10 = 1
So 239104-45-1 is a valid CAS Registry Number.
