The CAS Registry Mumber 185681-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,6,8 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 185681-39:
(8*1)+(7*8)+(6*5)+(5*6)+(4*8)+(3*1)+(2*3)+(1*9)=174
174 % 10 = 4
So 185681-39-4 is a valid CAS Registry Number.
