Check Digit Verification of cas no

The CAS Registry Mumber 138744-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,4 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138744-55:
(8*1)+(7*3)+(6*8)+(5*7)+(4*4)+(3*4)+(2*5)+(1*5)=155
155 % 10 = 5
So 138744-55-5 is a valid CAS Registry Number.
