Check Digit Verification of cas no

The CAS Registry Mumber 441715-26-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,1,7,1 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 441715-26:
(8*4)+(7*4)+(6*1)+(5*7)+(4*1)+(3*5)+(2*2)+(1*6)=130
130 % 10 = 0
So 441715-26-0 is a valid CAS Registry Number.

Salicylaldehyde-Promoted Cobalt-Catalyzed C-H/N-H Annulation of Indolyl Amides with Alkynes: Direct Synthesis of a 5-HT3 Receptor Antagonist Analogue

Huang, Mao-Gui,Shi, Shuai,Li, Ming,Liu, Yue-Jin,Liu, Yue-Jin

, p. 7094 - 7099 (2021/09/14)

A cobalt-catalyzed annulation of the C(sp2)-H/N-H bond of indoloamides with alkynes assisted by 8-aminoquinoline is reported for the synthesis of six-membered indololactams. The use of salicylaldehyde as the ligand is crucial for this transformation. The protocol has a broad scope for both alkynes and indoles. Preparing an active Co complex illustrates that salicylaldehyde plays a key role in the C-H activation step. The synthetic applications are proven by the gram-scale reaction and one-step construction of the multicyclic 5-HT3 receptor antagonist.

VLA-4 INHIBITORS

-

, (2008/06/13)

The present invention relates to a compound represented by the following formula (I): (wherein, W represents WA-A1 -WB - (in which, WA is substituted or unsubstituted aryl, etc., A1 is -NR1-, single bond, -C(O)-, etc., and WB is substituted or unsubstituted arylene, etc.), R is single bond, -NH-, -OCH2-, alkenylene, etc., X is -C(O) -CH2-, etc., and M is, for example, the following formula: (in which, R11, R12 and R13 each independently represents hydrogen, hydroxyl, amino, halogen, etc., R14 is hydrogen or lower alkyl, Y represents -CH2-O-, etc., Z is substituted or unsubstituted arylene, etc., A2 is single bond, etc, and R10 is hydroxyl or lower alkoxy)), or salt thereof; and a medicament containing the same. This compound or salt thereof selectively inhibits binding of cell adhesion molecules to VAL-4 and exhibits high bioavailability so that it is useful as a preventive and/or remedy for inflammatory diseases, autoimmune diseases, metastasis, bronchial asthma, rhinostenosis, diabetes, and the like.
