Check Digit Verification of cas no

The CAS Registry Mumber 78073-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,7 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78073-23:
(7*7)+(6*8)+(5*0)+(4*7)+(3*3)+(2*2)+(1*3)=141
141 % 10 = 1
So 78073-23-1 is a valid CAS Registry Number.
