Check Digit Verification of cas no

The CAS Registry Mumber 855773-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,7,7 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 855773-56:
(8*8)+(7*5)+(6*5)+(5*7)+(4*7)+(3*3)+(2*5)+(1*6)=217
217 % 10 = 7
So 855773-56-7 is a valid CAS Registry Number.

Diastereoselective route to novel fused or bridged tricyclic β-lactams through intramolecular nitrone-alkene cycloaddition of 2-azetidinone-tethered alkenylaldehydes - Synthetic applications to carbacephams and cyclic β-amino acid derivatives

Alcaide, Benito,Saez, Elena

, p. 1680 - 1693 (2007/10/03)

A convenient, regio- and stereoselective direct route to optically pure unusually fused or bridged tricyclic β-lactams has been developed by use of intramolecular nitrone-alkene cycloaddition (INAC) reactions of easily available monocyclic 2-azetidinone-t
