Check Digit Verification of cas no

The CAS Registry Mumber 1017572-74-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,7,5,7 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1017572-74:
(9*1)+(8*0)+(7*1)+(6*7)+(5*5)+(4*7)+(3*2)+(2*7)+(1*4)=135
135 % 10 = 5
So 1017572-74-5 is a valid CAS Registry Number.

Domino 1,4- And 1,6-Addition Reactions of Ketene Silyl Acetals to Dialkynyl Imines Promoted by Aluminum Chloride: Synthesis of Multifunctionalized β-Lactams

Hachiya, Iwao,Nakamura, Kenta,Hara, Masaya,Sato, Koki,Shimizu, Makoto

, p. 14770 - 14794 (2019/11/13)

Domino 1,4- and 1,6-addition reactions of ketene silyl acetals to dialkynyl imines are disclosed. Aluminum chloride promoted domino 1,4- and 1,6-addition reactions of ketene silyl acetals to dialkynyl imines to give a variety of alkenyl iminocyclobutenones in moderate to good yields. The chemoselective reduction of alkenyl iminocyclobutenones and the subsequent thermal rearrangement of resulting alkenyl aminocyclobutenones in the presence of appropriate amines provided cis or trans multifunctionalized β-lactams in moderate to high yields with good to high diastereoselectivities.
