Check Digit Verification of cas no

The CAS Registry Mumber 331993-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,9,9 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 331993-83:
(8*3)+(7*3)+(6*1)+(5*9)+(4*9)+(3*3)+(2*8)+(1*3)=160
160 % 10 = 0
So 331993-83-0 is a valid CAS Registry Number.

Enantioselective synthesis of cyclic enol ethers and all-carbon quaternary stereogenic centers through catalytic asymmetric ring-closing metathesis

Lee, Ai-Lan,Malcolmson, Steven J.,Puglisi, Alessandra,Schrock, Richard R.,Hoveyda, Amir H.

, p. 5153 - 5157 (2006)

The first examples of catalytic asymmetric ring-closing metathesis (ARCM) reactions of enol ethers are reported. To identify the most effective catalysts, various chiral Mo- and Ru-based catalysts were screened. Although chiral Ru catalysts (those that do

Enantioselective synthesis of cyclic allylboronates by Mo-catalyzed asymmetric ring-closing metathesis (ARCM). A one-pot protocol for net catalytic enantioselective cross metathesis

Jernelius, Jesper A.,Schrock, Richard R.,Hoveyda, Amir H.

, p. 7345 - 7351 (2004)

Mo-catalyzed asymmetric ring-closing metathesis (ARCM) reactions are used to synthesize cyclic allylboronates of high optical purity (89% ee to >98% ee). A one-pot procedure involving formation of allylboronates, Mo-catalyzed ARCM and functionalization of

Improved conditions for the proline-catalyzed aldol reaction of acetone with aliphatic aldehydes

Martínez, Alberto,Zumbansen, Kristina,D?hring, Arno,Van Gemmeren, Manuel,List, Benjamin

supporting information, p. 932 - 934 (2014/05/06)

The proline-catalyzed asymmetric aldol reaction between aliphatic aldehydes and acetone has, to date, remained underdeveloped. Challenges in controlling this reaction include avoiding undesired side reactions such as aldol condensation and self-aldolization. In recent years we have developed optimized conditions, which enable high yields and good to excellent enantioselectivities, and which are presented in this communication.
