Check Digit Verification of cas no

The CAS Registry Mumber 757-48-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,5 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 757-48:
(5*7)+(4*5)+(3*7)+(2*4)+(1*8)=92
92 % 10 = 2
So 757-48-2 is a valid CAS Registry Number.
