Check Digit Verification of cas no

The CAS Registry Mumber 40365-52-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,6 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40365-52:
(7*4)+(6*0)+(5*3)+(4*6)+(3*5)+(2*5)+(1*2)=94
94 % 10 = 4
So 40365-52-4 is a valid CAS Registry Number.
