Check Digit Verification of cas no

The CAS Registry Mumber 109744-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,4 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109744-33:
(8*1)+(7*0)+(6*9)+(5*7)+(4*4)+(3*4)+(2*3)+(1*3)=134
134 % 10 = 4
So 109744-33-4 is a valid CAS Registry Number.
