Check Digit Verification of cas no

The CAS Registry Mumber 2049-34-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,4 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2049-34:
(6*2)+(5*0)+(4*4)+(3*9)+(2*3)+(1*4)=65
65 % 10 = 5
So 2049-34-5 is a valid CAS Registry Number.
