Check Digit Verification of cas no

The CAS Registry Mumber 31594-55-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,9 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 31594-55:
(7*3)+(6*1)+(5*5)+(4*9)+(3*4)+(2*5)+(1*5)=115
115 % 10 = 5
So 31594-55-5 is a valid CAS Registry Number.

Synthesis of 1-Pyrroline by Denitrogenative Ring Expansion of Cyclobutyl Azides under Thermal Conditions

Ban, Kazuho,Miki, Yuya,Sajiki, Hironao,Sawama, Yoshinari,Tomita, Naohito

, p. 3481 - 3484 (2021/06/17)

We herein report an efficient and systematic synthesis of 1-pyrrolines from cyclobutyl azides under thermal and neutral conditions. The reaction proceeded without any additional reagents, and nitrogen was generated as the sole by-product. Furthermore, the generated 1-pyrrolines could be continuously transformed into pyrroles, N-Boc-amines, and oxaziridines in an one-pot manner. (Figure presented.).

Silyl-Substituted Thioimidates as Nitrile Ylide Equivalents

Padwa, Albert,Gasdaska, John R.,Haffmanns, Gunter,Rebello, Hector

, p. 1027 - 1035 (2007/10/02)

Treatment of silyl-substituted thioimidates with silver fluoride in the presence of a trapping agent produces dipolar cycloadducts formally derived from nitrile ylides.The ratio of cycloadducts obtained from the reaction of unsymmetrically substituted dip
