Check Digit Verification of cas no

The CAS Registry Mumber 76640-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,6,4 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76640-40:
(7*7)+(6*6)+(5*6)+(4*4)+(3*0)+(2*4)+(1*0)=139
139 % 10 = 9
So 76640-40-9 is a valid CAS Registry Number.

Conversion of some monocyclic β-lactams into novel di-β-lactams

Sharma,Gupta,Bindra,Sunita

, p. 3295 - 3298 (1980)

Monocyclic β-lactams (V & XI) carrying a carboxy function have been used to annelate the Schiff bases (II & X) using POCl3 in the presence of triethylamine to obtain the di-β-lactams (VI & XII). Alternately, (VI) could also be prepared by annelation of the Schiff base (IX) derived from the α-amino-β-lactam (VIII), with phenoxyacetyl chloride.

Synthesis of Some Novel Di- and Tri-β-lactams from Glycine

Sharma, S. D.,Mehra, Usha

, p. 545 - 551 (2007/10/02)

Annelation of the schiff bases (II) with appropriate β-lactam acids (I) results in the formation of di-β-lactams (III).Alternately IIIb can also be prepared as follows: Potassium carbethoxyacetonylglycinate (IV) on treatment with schiff base (IIb) using P
