Check Digit Verification of cas no

The CAS Registry Mumber 2070-75-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,7 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2070-75:
(6*2)+(5*0)+(4*7)+(3*0)+(2*7)+(1*5)=59
59 % 10 = 9
So 2070-75-9 is a valid CAS Registry Number.
