Check Digit Verification of cas no

The CAS Registry Mumber 145243-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,2,4 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 145243-01:
(8*1)+(7*4)+(6*5)+(5*2)+(4*4)+(3*3)+(2*0)+(1*1)=102
102 % 10 = 2
So 145243-01-2 is a valid CAS Registry Number.
