Check Digit Verification of cas no

The CAS Registry Mumber 1185746-34-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,7,4 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1185746-34:
(9*1)+(8*1)+(7*8)+(6*5)+(5*7)+(4*4)+(3*6)+(2*3)+(1*4)=182
182 % 10 = 2
So 1185746-34-2 is a valid CAS Registry Number.
