128399-07-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128399-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,9 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128399-07:
(8*1)+(7*2)+(6*8)+(5*3)+(4*9)+(3*9)+(2*0)+(1*7)=155
155 % 10 = 5
So 128399-07-5 is a valid CAS Registry Number.

Novel ortho-Alkoxy-Substituted Phosphorus Ylides and Their Stereoselectivity in Wittig Reactions

Jeganathan, Suruliappa,Tsukamoto, Masamitsu,Schlosser, Manfred

, p. 109 - 111 (2007/10/02)

The stereochemistry of the reactions between tris(2-methoxymethoxypheny)phosphonioethanide (1f), -butanide (2f), and -phenyl-methanide (3f) and a variety of aldehydes was investigated.Ylides having a β-unbranched aliphatic sidechain, such as 2f, and saturated straight-chain aldehydes give olefins with unprecedented cis-selectivity (cis/trans ca. 200:1).
