Check Digit Verification of cas no

The CAS Registry Mumber 172613-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,6,1 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 172613-65:
(8*1)+(7*7)+(6*2)+(5*6)+(4*1)+(3*3)+(2*6)+(1*5)=129
129 % 10 = 9
So 172613-65-9 is a valid CAS Registry Number.

Asymmetric Transfer Hydrogenation: Dynamic Kinetic Resolution of α-Amino Ketones

Gediya, Shweta K.,Clarkson, Guy J.,Wills, Martin

, p. 11309 - 11330 (2020/10/12)

A series of α-amino ketones were reduced using asymmetric transfer hydrogenation (ATH) through a dynamic kinetic resolution (DKR). The protecting group was matched to the reducing agent, and following optimization, a series of substrates were investigated, giving products in high diastereoselectivity, over 99% ee in several cases and full conversion. The methodology was applied to the enantioselective synthesis of an MDM2-p53 inhibitor precursor.

Enantioselective N-H insertion reaction of α-aryl α-diazoketones: An efficient route to chiral α-aminoketones

Xu, Bin,Zhu, Shou-Fei,Zuo, Xiao-Dong,Zhang, Zhi-Chao,Zhou, Qi-Lin

, p. 3913 - 3916 (2014/05/06)

A highly enantioselective N-H insertion reaction of α-diazoketones was developed by using cooperative catalysis by dirhodium(II) carboxylates and chiral spiro phosphoric acids. The insertion reaction provides a new access route to diverse chiral α-aminoketones, which are versatile building blocks in organic synthesis, with fast reaction rates, good yields and high enantioselectivity under mild and neutral conditions.
