33978-37-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33978-37-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,7 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 33978-37:
(7*3)+(6*3)+(5*9)+(4*7)+(3*8)+(2*3)+(1*7)=149
149 % 10 = 9
So 33978-37-9 is a valid CAS Registry Number.

One-pot solvent-free reductive amination with a solid ammonium carbamate salt from CO2 and amine

Kang, Philjun,Lee, Kyu Myung,Lee, Won Koo,Lee, Kyu Hyung,Lee, Byeongno,Cho, Jaeheung,Hur, Nam Hwi

, p. 46203 - 46207 (2015/02/19)

Many amines are liquid and their handling is inconvenient compared with the corresponding solids. We transformed a liquid (S)-(-)-1-phenylethylamine 1 to the corresponding neutral solid form 2 by reacting with carbon dioxide. We performed reductive aminat

Synthesis, enzymic degradation, lipophilic properties, and biological activity of [D-alanine2, t-butylglycine 5]enkephalin amide

Fauchere,Petermann

, p. 824 - 831 (2007/10/02)

L-C(a)-t-Butylglycine (Bug), its amide, methyl ester, and N(a)-t-butoxycarbonyl derivative were prepared by an asymmetric synthesis, and the Hansch side-chain hydrophobic (lipophilicity) parameter determined. A new enkephalin analogue, H . Tyr-D-Ala-Gly-Phe-Bug . HN2 was synthesized which is pharmacologically active in two in vitro assays and strongly resistant against a number of enzymes in vitro.
