Check Digit Verification of cas no

The CAS Registry Mumber 205595-50-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,5,9 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 205595-50:
(8*2)+(7*0)+(6*5)+(5*5)+(4*9)+(3*5)+(2*5)+(1*0)=132
132 % 10 = 2
So 205595-50-2 is a valid CAS Registry Number.
