Check Digit Verification of cas no

The CAS Registry Mumber 1591623-49-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,1,6,2 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1591623-49:
(9*1)+(8*5)+(7*9)+(6*1)+(5*6)+(4*2)+(3*3)+(2*4)+(1*9)=182
182 % 10 = 2
So 1591623-49-2 is a valid CAS Registry Number.
