141316-26-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141316-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,3,1 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 141316-26:
(8*1)+(7*4)+(6*1)+(5*3)+(4*1)+(3*6)+(2*2)+(1*6)=89
89 % 10 = 9
So 141316-26-9 is a valid CAS Registry Number.

Synthesis of chiral acetylenic analogs of the plant hormone abscisic acid
Rose,Abrams,Shaw
, p. 443 - 450 (2007/10/02)
Syntheses of optically active acetylenic analogs of abscisic acid are described. The key step involves the diastereoselective alkylation of the (2S,3S)-butanediol ketal of oxoisophorone, which produces a 3:1 mixture of separable diastereoisomers. The abso
