Check Digit Verification of cas no

The CAS Registry Mumber 3782-76-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,8 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3782-76:
(6*3)+(5*7)+(4*8)+(3*2)+(2*7)+(1*6)=111
111 % 10 = 1
So 3782-76-1 is a valid CAS Registry Number.
