Check Digit Verification of cas no

The CAS Registry Mumber 42423-25-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,2 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42423-25:
(7*4)+(6*2)+(5*4)+(4*2)+(3*3)+(2*2)+(1*5)=86
86 % 10 = 6
So 42423-25-6 is a valid CAS Registry Number.
