Check Digit Verification of cas no

The CAS Registry Mumber 492-87-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 492-87:
(5*4)+(4*9)+(3*2)+(2*8)+(1*7)=85
85 % 10 = 5
So 492-87-5 is a valid CAS Registry Number.

Glutarimide Alkaloids Through Multicomponent Reaction Chemistry

Konstantinidou, Markella,Kurpiewska, Katarzyna,Kalinowska-T?uscik, Justyna,D?mling, Alexander

supporting information, p. 6714 - 6719 (2018/11/25)

A concise four step synthetic route for glutarimide alkaloids of high biological interest is presented. The scaffold is accessed via an Ugi four component reaction, hereby introducing two points of variation. This is followed by a hydrolysis, a cyclization under mild conditions, and an amine deprotection. The diastereomers of the cyclized intermediate can be easily separated, thus leading to optically pure alkaloids. By this route, four natural products and ten derivatives were synthesized. The scope and limitations of the synthetic methodology were investigated.

Enantioselective synthesis of glutarimide alkaloids cordiarimides A, B, crotonimides A, B, and julocrotine

Teng, Bo,Zheng, Jianfeng,Huang, Huiying,Huang, Peiqiang

, p. 1312 - 1318 (2011/10/31)

Five glutarimide alkaloids cordiarimide A (5), cordiarimide B (6), crotonimide A (3), crotonimide B (4), and julocrotine (2) have been synthesized starting from Boc-L-glutamine (7). The benzylic alcohol chiral centre of cordiarimides B (6) has been established in 6:1 diastereoselectivity by catalytic asymmetric hydrogenation using Zhou's catalytic system Pd(CF 3CO2)2/(R,R)-Me-DuPhos.
