Check Digit Verification of cas no

The CAS Registry Mumber 156881-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,8,8 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 156881-63:
(8*1)+(7*5)+(6*6)+(5*8)+(4*8)+(3*1)+(2*6)+(1*3)=169
169 % 10 = 9
So 156881-63-9 is a valid CAS Registry Number.

Chiral electrophilic 'glycinal' equivalents. New synthons for optically active α-amino acids and 4-substituted 2-oxazolidinones

Matsunaga, Hirofumi,Ishizuka, Tadao,Kunieda, Takehisa

, p. 1275 - 1294 (2007/10/03)

The thermal reaction of 3-[(1S)-2-alkoxy-1-apocamphanecarbonyl]-2-oxazolones (21a-c) with dialkyl azodicarboxylates (9) results in exclusive formation of [4 + 2] type cycloadducts (22 and 23) with moderate levels of diastereofacial selection (up to 72% d.e.). The diastereomers thus obtained were readily purified and subsequent treatment with acidic methanol followed by removal of the auxiliary with LiBH4/MeOH (1:2) gave optically pure 4-methoxy-5-hydrazino-2-oxazolidinones (26 and 27), which serve as α-aminoaldehyde templates useful for the synthesis of a wide variety of optically active α-amino acids as well as 4-alkyl and 4-aryl-2-oxazolidinones.
