1334521-60-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1334521-60-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,5,2 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1334521-60:
(9*1)+(8*3)+(7*3)+(6*4)+(5*5)+(4*2)+(3*1)+(2*6)+(1*0)=126
126 % 10 = 6
So 1334521-60-6 is a valid CAS Registry Number.

Asymmetric synthesis of monocyclic β-lactams from l-cysteine using photochemistry
Lu, Xiao,Long, Timothy E.
, p. 5051 - 5054 (2011/10/09)
An asymmetric method to synthesize cis-configured β-lactams using photochemistry has been developed. Aerobic photo-oxidation of l-cysteine-derived thiazolidine hydroxamate esters afforded C-3 hydroxylated products which when cyclized and deprotected gave
