Check Digit Verification of cas no

The CAS Registry Mumber 1242422-05-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,4,2 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1242422-05:
(9*1)+(8*2)+(7*4)+(6*2)+(5*4)+(4*2)+(3*2)+(2*0)+(1*5)=104
104 % 10 = 4
So 1242422-05-4 is a valid CAS Registry Number.
