Check Digit Verification of cas no

The CAS Registry Mumber 52497-56-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,4,9 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 52497-56:
(7*5)+(6*2)+(5*4)+(4*9)+(3*7)+(2*5)+(1*6)=140
140 % 10 = 0
So 52497-56-0 is a valid CAS Registry Number.

Cross-coupling of vinylethylene carbonates with arylboronic acids catalyzed by in situ generated palladium nanoparticles in water

Mao, Yuxue,Zhai, Xing,Khan, Ajmal,Cheng, Jiong,Wu, Xue,Zhang, Yong Jian

supporting information, p. 3268 - 3271 (2016/07/11)

A practical and greener method of the cross-coupling of vinylethylene carbonates (VECs) with arylboronic acids has been described. The coupling reaction was catalyzed by in situ generated palladium nanoparticles (PdNPs) without any ligands and additional stabilizers in water under ambient conditions to provide useful 4-hydroxylprenylarenes and their derivatives in good to high yields.

Convergent synthesis of (2R,3R,8R,9R)-N-Boc-ADDA

, p. 5015 - 5021 (2008/12/20)

(Figure Presented) The convergent synthesis of N-Boc-(2R,3R,8R,9R,4E,6E)-3- amino-9-methoxy-2,6,8-trimethyl-10-phenyldecadenoic acid (enantio-N-Boc-ADDA) is reported. Our flexible approach takes advantage of highly efficient non-aldol aldol and cross-metathesis methodologies.

Stereospecific synthesis of aldols

, (2008/06/13)

Methods are provided for preparing all four diastereomers of 2-alkyl-3-hydroxyalkanals, 2-alkyl-3-silyloxyalkanals, and the like, with high enantiocontrol, using non-aldol chemistry. The synthetic methods also provide novel, stereospecific routes to polyp
