Check Digit Verification of cas no

The CAS Registry Mumber 13142-05-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,4 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13142-05:
(7*1)+(6*3)+(5*1)+(4*4)+(3*2)+(2*0)+(1*5)=57
57 % 10 = 7
So 13142-05-7 is a valid CAS Registry Number.
