Check Digit Verification of cas no

The CAS Registry Mumber 9071-54-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,7 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 9071-54:
(6*9)+(5*0)+(4*7)+(3*1)+(2*5)+(1*4)=99
99 % 10 = 9
So 9071-54-9 is a valid CAS Registry Number.
