Check Digit Verification of cas no

The CAS Registry Mumber 149744-62-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,7,4 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 149744-62:
(8*1)+(7*4)+(6*9)+(5*7)+(4*4)+(3*4)+(2*6)+(1*2)=167
167 % 10 = 7
So 149744-62-7 is a valid CAS Registry Number.
