Check Digit Verification of cas no

The CAS Registry Mumber 1393596-52-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,5,9 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1393596-52:
(9*1)+(8*3)+(7*9)+(6*3)+(5*5)+(4*9)+(3*6)+(2*5)+(1*2)=205
205 % 10 = 5
So 1393596-52-5 is a valid CAS Registry Number.

Regio- and diastereoselective synthesis of β-lactam-triazole hybrids via passerini/CuAAC sequence

Alcaide, Benito,Almendros, Pedro,Aragoncillo, Cristina,Callejo, Ricardo,Ruiz, M. Pilar,Torres, M. Rosario

experimental part, p. 6917 - 6928 (2012/09/22)

Passerini (P-3CR) and Passerini-Smiles reactions were investigated in azetidine-2,3-diones, affording the corresponding 3,3-disubstituted-β- lactams with complete diastereoselectivity in high yields. The study has been carried out using different isocyanides, carboxylic acids, and phenols showing the scope of both reactions. In addition, the regioselective synthesis of highly functionalized β-lactam-triazole hybrids has been developed via a Passerini/CuAAC sequence. Interestingly, the use of dialkynes/diazides or trialkynes/triazides as linkers in the CuAAC step has allowed the synthesis of C2 and C3 symmetric β-lactam-triazole hybrids, respectively.
