Check Digit Verification of cas no

The CAS Registry Mumber 1426257-10-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,2,5 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1426257-10:
(9*1)+(8*4)+(7*2)+(6*6)+(5*2)+(4*5)+(3*7)+(2*1)+(1*0)=144
144 % 10 = 4
So 1426257-10-4 is a valid CAS Registry Number.

Gold-catalyzed oxidative cyclization of chiral homopropargyl amides: Synthesis of enantioenriched γ-lactams

Shu, Chao,Liu, Meng-Qi,Wang, Shan-Shan,Li, Long,Ye, Long-Wu

, p. 3292 - 3299 (2013/06/27)

A gold-catalyzed tandem cycloisomerization/oxidation of homopropargyl amides has been developed, which provides ready access to synthetically useful chiral γ-lactams with excellent ee by combining the chiral tert-butylsulfinimine chemistry and gold cataly
