Check Digit Verification of cas no

The CAS Registry Mumber 2092-56-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,9 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2092-56:
(6*2)+(5*0)+(4*9)+(3*2)+(2*5)+(1*6)=70
70 % 10 = 0
So 2092-56-0 is a valid CAS Registry Number.
