Check Digit Verification of cas no

The CAS Registry Mumber 73839-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,3 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73839-40:
(7*7)+(6*3)+(5*8)+(4*3)+(3*9)+(2*4)+(1*0)=154
154 % 10 = 4
So 73839-40-4 is a valid CAS Registry Number.
