84323-78-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84323-78-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,2 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84323-78:
(7*8)+(6*4)+(5*3)+(4*2)+(3*3)+(2*7)+(1*8)=134
134 % 10 = 4
So 84323-78-4 is a valid CAS Registry Number.

, p. 733 - 736 (2007/10/02)
A variety of alkyl or phenyl-substituted thia-crown ethers were prepared in two or three steps via bromoalkoxylation reactions of olefins.Dialkyl- and phenyl-substituted mono- and dithia-crown ethers were obtained as single compounds, whereas monoalkyl-su
