789-54-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 789-54-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,8 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 789-54:
(5*7)+(4*8)+(3*9)+(2*5)+(1*4)=108
108 % 10 = 8
So 789-54-8 is a valid CAS Registry Number.

Monooxychlorophosphine as a novel and efficient ligand for palladium-catalyzed Suzuki-Miyaura cross-coupling of aryl chlorides

Mai, Wenpeng,Lv, Guanghua,Gao, Lianxun

, p. 2247 - 2251 (2007)

A new sterically hindered monooxychlorophosphine was synthesized and the complex generated in situ from its reaction with Pd2(dba)3 promoted the Suzuki-Miyaura reactions of arylboronic acids with aryl chlorides in good yields. Georg Thieme Verlag Stuttgart.

NMR and X-ray crystallographic studies of unsymmetrical 25,26;27,28-dibridged para-tert-butyl calix[4]arene bisphosphites with a large "through-space" P-P coupling
