49776-70-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 49776-70-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,7 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 49776-70:
(7*4)+(6*9)+(5*7)+(4*7)+(3*6)+(2*7)+(1*0)=177
177 % 10 = 7
So 49776-70-7 is a valid CAS Registry Number.

Rearrangement Approaches to Cyclic Skeletons. IV. The Total Synthesis of (+/-)-Pinguisone and (+/-)-Deoxopinguisone Based on Photochemical Acyl Migration of a Bicyclonon-6-en-2-one

Uyehara, Tadao,Kabasawa, Yasuhiro,Kato, Tadahiro

, p. 2521 - 2528 (2007/10/02)

The total synthesis of (+/-)-Pinguisone (2) and (/-)-deoxopinguisone (3), fused ring sesquiterpenes, has been achieved starting from 1-methoxy-3,4,5-trimethylbenzene. 1-Methoxy-4,5,endo-8-trimethylbicyclonon-5-en-2-one (9) was prepared selectively via facial selective Diels-Alder reaction of the diene derived from the benzene and 2-chloroacrylonitrile.Ring enlargement of 9 using (CH3)3SiCHN2 and BF3 etherate gave the corresponding bicyclooct-en-2-one (8).The photochemical acyl migration of 8 gave the fused-ring compound (7).The fourth methyl was introduced selectively by the conjugate addition of (CH3)2CuLi to the spironon-8-ene-3,2'-dioxolan>-7-one prepared from 7.Each furan ring of 2 and 3 was constructed via the corresponding butenolide derived from the γ-keto acid by acid-catalyzed dehydration.
