Check Digit Verification of cas no

The CAS Registry Mumber 1471991-04-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,7,1,9,9 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1471991-04:
(9*1)+(8*4)+(7*7)+(6*1)+(5*9)+(4*9)+(3*1)+(2*0)+(1*4)=184
184 % 10 = 4
So 1471991-04-4 is a valid CAS Registry Number.

Pd(ii)-catalyzed alkylation of unactivated C(sp3)-H bonds: Efficient synthesis of optically active unnatural α-amino acids

Chen, Kai,Hu, Fang,Zhang, Shuo-Qing,Shi, Bing-Feng

, p. 3906 - 3911 (2013/09/23)

A palladium-catalyzed alkylation of primary and secondary C(sp 3)-H bonds with alkyl iodides and/or bromides for the synthesis of optically active unnatural α-amino acids (α-AAs) is described. This process is scalable and tolerates a variety of functional groups with complete retention of chirality, providing an efficient new strategy for the synthesis of various unnatural α-amino acid derivatives.
