Check Digit Verification of cas no

The CAS Registry Mumber 1333118-34-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,1,1 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1333118-34:
(9*1)+(8*3)+(7*3)+(6*3)+(5*1)+(4*1)+(3*8)+(2*3)+(1*4)=115
115 % 10 = 5
So 1333118-34-5 is a valid CAS Registry Number.

D-Mannitol-derived novel chiral thioureas: Synthesis and application in asymmetric Henry reactions

Liu, Miaoxi,Ji, Nan,Wang, Li,Liu, Peng,He, Wei

, p. 999 - 1004 (2018/02/23)

Five novel thioureas have been obtained through multi-step reactions from D-Mannitol as starting material and applied as catalysts in the asymmetric Henry reaction. Using catalyst 7a, (1S,2R)-2-nitro-1-phenylpropan-1-ol containing two chiral centers was o

Modular bifunctional chiral thioureas as versatile organocatalysts for highly enantioselective aza-Henry reaction and michael addition

Li, Hua,Zhang, Xu,Shi, Xin,Ji, Nan,He, Wei,Zhang, Shengyong,Zhang, Bangle

, p. 2264 - 2274 (2012/11/06)

A series of new modular bifunctional chiral thiourea organocatalysts were synthesized from natural Cinchona alkaloids and amino acids, and their performance in the aza-Henry reaction of nitroalkanes to imines, the Michael addition of acetylacetone to nitroolefins and the Michael addition of acetone to nitroolefins was investigated. Under the mild conditions, the important building blocks β-nitro amines and γ-nitro carbonyl compounds could be obtained in good yields (up to 95%) with excellent enantioselectivities (up to 99% ee) and diastereoselectivity (up to 17:1).
