1438279-61-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1438279-61-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,2,7 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1438279-61:
(9*1)+(8*4)+(7*3)+(6*8)+(5*2)+(4*7)+(3*9)+(2*6)+(1*1)=188
188 % 10 = 8
So 1438279-61-8 is a valid CAS Registry Number.

Access to trans-3,4-Dihydroxy-2-alkylpyrrolidines and piperidines by use of stereodefined cyclic N,O-Acetals as a Diversity-generating element

Kang, Soyeong,Kim, Dong-Gil,Rhee, Young Ho

, p. 16391 - 16396 (2014)

A highly efficient and stereoselective synthetic pathway towards trans-3,4-dihydroxy-2-alkylpyrrolidines and piperidines is described. The nature of the protecting groups on the hydroxyl moieties played a crucial role on the trans selectivity. By using this method, a concise total synthesis of (-)-2-epilentiginosine has been achieved.

Synthetic strategy for cyclic amines: A stereodefined cyclic N,O-acetal as a stereocontrol and diversity-generating element

Kim, Haejin,Lim, Wontaeck,Im, Donghong,Kim, Dong-Gil,Rhee, Young Ho

supporting information, p. 12055 - 12058 (2013/01/16)

In control: A new synthetic strategy towards cyclic amines was developed and exploits a stereodefined cyclic N,O-acetal as the key stereocontrol and diversity-generating element. The cyclic N,O-acetal was prepared from the sequential asymmetric hydroamina
