Check Digit Verification of cas no

The CAS Registry Mumber 156995-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,9,9 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 156995-23:
(8*1)+(7*5)+(6*6)+(5*9)+(4*9)+(3*5)+(2*2)+(1*3)=182
182 % 10 = 2
So 156995-23-2 is a valid CAS Registry Number.
