Check Digit Verification of cas no

The CAS Registry Mumber 29568-12-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,5,6 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 29568-12:
(7*2)+(6*9)+(5*5)+(4*6)+(3*8)+(2*1)+(1*2)=145
145 % 10 = 5
So 29568-12-5 is a valid CAS Registry Number.

Palladacycle-catalyzed carbonylation of aryl iodides or bromides with aryl formates

Chen, Guangwei,Leng, Yuting,Yang, Fan,Wang, Shiwei,Wu, Yangjie

, p. 1488 - 1494 (2014/01/06)

An efficient palladacycle-catalyzed aromatic carbonylation reaction of aryl formates with aryl iodides or bromides has been developed. Commercially available and easily prepared aryl formates were employed as carbonyl sources without the use of external carbon monoxide. The present catalytic system shows broad functional group tolerance and affords aryl benzoate derivatives in good to excellent yields. Copyright

One-pot synthesis of cyclic triamides with a triangular cavity from trans-stilbene and diphenylacetylene monomers

Yokoyama, Akihiro,Maruyama, Takurou,Tagami, Kei,Masu, Hyuma,Katagiri, Kosuke,Azumaya, Isao,Yokozawa, Tsutomu

supporting information; experimental part, p. 3207 - 3210 (2009/05/11)

(Chemical Equation Presented) Base-promoted self-condensation reactions of trans-stilbene and diphenylacetylene monomers bearing 4-alkylamino and 4′-methoxycarbonyl groups were investigated. Reactions of N-propyl monomers under pseudohigh-dilution conditions (a THF solution of monomer was added dropwise to a THF solution of LiHMDS) afforded the corresponding cyclic triamides in good yields. X-ray crystallographic analysis showed that these cyclic triamides possessed an almost equilateral triangle structure with a cavity surrounded by tilted benzene rings.
