The CAS Registry Mumber 118657-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,5 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 118657-32:
(8*1)+(7*1)+(6*8)+(5*6)+(4*5)+(3*7)+(2*3)+(1*2)=142
142 % 10 = 2
So 118657-32-2 is a valid CAS Registry Number.
