Check Digit Verification of cas no

The CAS Registry Mumber 55442-39-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,4,4 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 55442-39:
(7*5)+(6*5)+(5*4)+(4*4)+(3*2)+(2*3)+(1*9)=122
122 % 10 = 2
So 55442-39-2 is a valid CAS Registry Number.
