Check Digit Verification of cas no

The CAS Registry Mumber 30727-23-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,7,2 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 30727-23:
(7*3)+(6*0)+(5*7)+(4*2)+(3*7)+(2*2)+(1*3)=92
92 % 10 = 2
So 30727-23-2 is a valid CAS Registry Number.
