Check Digit Verification of cas no

The CAS Registry Mumber 6239-07-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,3 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6239-07:
(6*6)+(5*2)+(4*3)+(3*9)+(2*0)+(1*7)=92
92 % 10 = 2
So 6239-07-2 is a valid CAS Registry Number.
