Check Digit Verification of cas no

The CAS Registry Mumber 188300-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,3,0 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 188300-52:
(8*1)+(7*8)+(6*8)+(5*3)+(4*0)+(3*0)+(2*5)+(1*2)=139
139 % 10 = 9
So 188300-52-9 is a valid CAS Registry Number.

Novel asymmetric phenylselenium-induced lactamizations of olefinic amides: Stereoselective routes to α- and β-amino acids

Chung, Sung-Kee,Jeong, Tae-Heum,Kang, Dong-Ho

, p. 969 - 976 (2007/10/03)

Organoselenium-induced cyclofunctionalization of the (S)-N-(α,β-unsaturated) acylprolinamides 1, 7 and 14 has been found to produce the 7-membered bislactam products 2 and 15, or the 6-membered phenylselenolactam products 8 and 9 depending on the substitution pattern of the enone moiety of the starting material. The structural identities and stereochemistry of the cyclized products have been determined by X-ray diffraction, and the diastereoselectivity in the formation of the 7-membered ring bislactam product was found to be 91.6% de. The mechanism of the cyclolactamization is discussed.

A diastereoselective phenylselenium-induced lactamization of olefimic amides. A possible route to α- and β-amino acid derivatives

Chung, Sung-Kee,Jeong, Tae-Heum,Kang, Dong-Ho

, p. 5 - 9 (2007/10/03)

The organoselenium-induced cyclofunctionalization of (S)-N-(α,β-unsaturated-acyl)prolinamides was found to produce with a high degree of chirality transfer, 7- and 6-membered bislactam derivatives depending on the substitution pattern of the starting material.
