Check Digit Verification of cas no

The CAS Registry Mumber 1443497-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,4,9 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1443497-75:
(9*1)+(8*4)+(7*4)+(6*3)+(5*4)+(4*9)+(3*7)+(2*7)+(1*5)=183
183 % 10 = 3
So 1443497-75-3 is a valid CAS Registry Number.

Nickel-Catalyzed Intramolecular Hydroalkenylation of Imines

Feng, Wei-Min,Li, Tian-Yu,Xiao, Li-Jun,Zhou, Qi-Lin

supporting information, p. 7900 - 7904 (2021/10/12)

A ligand-enabled nickel-catalyzed intramolecular hydroalkenylation of imines with unactivated alkenes has been developed. A variety of five- and six-membered cyclic allylic amines were synthesized in high yields. The use of both wide-bite-angle diphosphine ligand and Br?nsted acid is crucial for realizing the reaction. Preliminary investigation of the asymmetric intramolecular hydroalkenylation of imines shows promising potential for the application of the method in the synthesis of enantio-enriched cyclic allylic amines.
