Check Digit Verification of cas no

The CAS Registry Mumber 1178-23-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,7 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1178-23:
(6*1)+(5*1)+(4*7)+(3*8)+(2*2)+(1*3)=70
70 % 10 = 0
So 1178-23-0 is a valid CAS Registry Number.
