Check Digit Verification of cas no

The CAS Registry Mumber 273211-30-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,3,2,1 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 273211-30:
(8*2)+(7*7)+(6*3)+(5*2)+(4*1)+(3*1)+(2*3)+(1*0)=106
106 % 10 = 6
So 273211-30-6 is a valid CAS Registry Number.
