Check Digit Verification of cas no

The CAS Registry Mumber 1446348-69-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,6,3,4 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1446348-69:
(9*1)+(8*4)+(7*4)+(6*6)+(5*3)+(4*4)+(3*8)+(2*6)+(1*9)=181
181 % 10 = 1
So 1446348-69-1 is a valid CAS Registry Number.

Bioinspired Synthesis of the Central Core of Halichonadin H: The Passerini Reaction in a Hypothetical Biosynthesis of Marine Natural Products

Ichikawa, Yoshiyasu,Yamasaki, Toshiki,Nakanishi, Keisuke,Udagawa, Yutaro,Hosokawa, Seijiro,Masuda, Toshiya

, p. 2305 - 2310 (2019)

A pathway is proposed for the biosynthesis of the unique homodimeric terpene, halichonadin H. The proposed biosynthetic pathway involves two key Passerini reactions of eudesmane-type terpene isocyanides. The Passerini reaction of a model terpene isocyanide and formaldehyde afforded an α-hydroxy acetamide, which was further subjected to oxidation and a second Passerini reaction. This reaction sequence furnished an α-hydroxy malonamide connected with two identical terpene units which is the identical structural motif found in halichonadin H.

A biomimetic approach to terpenes isolated from marine sponges: A Ugi coupling reaction in a hypothetical biosynthesis

Saito, Kenta,Nishimori, Ayumu,Kotsuki, Hiyoshizo,Nakano, Keiji,Ichikawa, Yoshiyasu

, p. 757 - 761 (2013/05/09)

A unique pathway for the biosynthesis of marine sponge terpenes is proposed. Based on this proposal, a biomimetic approach using a Ugi coupling reaction has been designed and applied to the efficient construction of the right-side, peptide-like portions of boneratamides and exigurin.
