Check Digit Verification of cas no

The CAS Registry Mumber 112081-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,0,8 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 112081-87:
(8*1)+(7*1)+(6*2)+(5*0)+(4*8)+(3*1)+(2*8)+(1*7)=85
85 % 10 = 5
So 112081-87-5 is a valid CAS Registry Number.

Pd(0) catalyzed intramolecular Heck reaction: a versatile route for the synthesis of 2-aryl substituted 5-, 6-, and 7-membered O-containing heterocycles

Samanta, Shubhankar,Mohapatra, Hemakesh,Jana, Rathin,Ray, Jayanta K.

scheme or table, p. 7153 - 7156 (2009/04/10)

An efficient and convenient method for the synthesis of 2-aryl substituted tetrahydropyran, tetrahydrofuran, and oxepine derivatives via intramolecular palladium catalyzed cyclization is developed. The two exo-cyclic double bonds at adjacent carbon atoms

CONJUGATED EXOCYCLIC DIENES BY ADDITION OF 2-(BENZYLOXYMETHYL)-3-(BROMOZINCMETHYL)-1,3-BUTADIENE TO ALDEHYDES, KETONES AND IMINES FOLLOWED BY Pd(O)-CATALYZED CYCLIZATION

Louw, J. van der,Slagt, M.,Baan, J.L. van der,Bickelhaupt, F,Klumpp, G.W.

, p. 5497 - 5500 (2007/10/02)

Reaction of 2-(benzyloxymethyl)-3-(bromozincmethyl)-1,3-butadiene with aldehydes, ketones and imines afforded addition products 6, which underwent Pd(O)-catalyzed cyclization to the conjugated exocyclic dienes 7.

2-Dimethylaminomethyl-3-trimethylsilylmethylbuta-1,3-diene as a Synthetic Equivalent of 2,2'-Biallyl Zwitterionic Species

Hosomi, Akira,Hoashi, Koichiro,Kohra, Shinya,Tominaga, Yoshinori,Otaka, Ken,Sakurai, Hideki

, p. 570 - 571 (2007/10/02)

The title compound reacts with nucleophiles followed by electrophiles in tandem or in the reverse order smoothly to give 1,2-dimethylenecyclohexanes and their oxa analogues; thus this reagent acts as the synthetic equivalent of 2,2'-biallyl zwitterionic s
