Check Digit Verification of cas no

The CAS Registry Mumber 5762-83-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,6 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5762-83:
(6*5)+(5*7)+(4*6)+(3*2)+(2*8)+(1*3)=114
114 % 10 = 4
So 5762-83-4 is a valid CAS Registry Number.
