Check Digit Verification of cas no

The CAS Registry Mumber 2744-49-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,4 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2744-49:
(6*2)+(5*7)+(4*4)+(3*4)+(2*4)+(1*9)=92
92 % 10 = 2
So 2744-49-2 is a valid CAS Registry Number.
