Flammable

Check Digit Verification of cas no

The CAS Registry Mumber 7328-91-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,2 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7328-91:
(6*7)+(5*3)+(4*2)+(3*8)+(2*9)+(1*1)=108
108 % 10 = 8
So 7328-91-8 is a valid CAS Registry Number.

Continuous amination of propanediols in supercritical ammonia

Fischer, Achim,Mallat, Tamas,Baiker, Alfons

, p. 351 - 354 (2007/10/03)

Enhancements in selectivity by a factor of 4 to 18 were observed in the near critical regions of ammonia during the Co- and Ni-catalyzed synthesis of 1,3-diamino-propanes. These results are attributed to the higher concentration of ammonia at the surface of the catalyst, which favors the amination and suppresses degredation reactions.

Cosmetic composition containing an amide-amine type condensate, and a cosmetic treating process using said condensate

-

, (2008/06/13)

A cosmetic composition for improving the suppleness of the skin or hair and for protecting the keratin of the skin or hair from degradation by atmospheric agents or light comprises in a cosmetic or dermatologic acceptable vehicle a saturated condensate resulting from the polyaddition of a bis-acrylamide and a sterically hindered primary diamine, the condensate being saturated by hydrogenation or by addition of a thiol or an amine on the double bonds of the acrylamide residue.

Silicone containing bis-thioether aromatic amines

-

, (2008/06/13)

A silicone containing bis-thioether aromatic amine has a chemical structure wherein an aromatic nucleus at each end of the chemical radical is chemically bonded to the remainder of the chemical radical by either sulfur, sulfoxide or sulfone.
