100108-94-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 100108-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,1,0 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 100108-94:
(8*1)+(7*0)+(6*0)+(5*1)+(4*0)+(3*8)+(2*9)+(1*4)=59
59 % 10 = 9
So 100108-94-9 is a valid CAS Registry Number.

STEREOSELECTIVE ALDOL ADDITIONS TO α-ALKOXY ALDEHYDES USING THIOESTER SILYL KETENE ACETALS.

Gennari, Cesare,Bernardi, Anna,Poli, Giovanni,Scolastico, Carlo

, p. 2373 - 2376 (1985)

Relative stereochemistry (chelation) effectively controls internal stereochemistry (syn-anti) in the addition of thiopropionate equivalents to O-benzyl lactic aldehyde.

LEWIS ACID MEDIATED ALDOL CONDENSATIONS USING THIOESTER SILYL KETENE ACETALS

Gennari, Cesare,Beretta, M. Grazia,Bernardi, Anna,Moro, Giorgio,Scolastico, Carlo,Todeschini, Roberto

, p. 893 - 910 (2007/10/02)

BF3-OEt2 mediated thioester silylketene acetal additions to aldehydes are stereoconvergent and give high anti-syn ratios and good chemical yields.An acyclic transition state model was hypothesized in order to account for the observed selectivity.Theoretic
