Check Digit Verification of cas no

The CAS Registry Mumber 178744-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,7,4 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 178744-44:
(8*1)+(7*7)+(6*8)+(5*7)+(4*4)+(3*4)+(2*4)+(1*4)=180
180 % 10 = 0
So 178744-44-0 is a valid CAS Registry Number.
