129171-83-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129171-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,7 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129171-83:
(8*1)+(7*2)+(6*9)+(5*1)+(4*7)+(3*1)+(2*8)+(1*3)=131
131 % 10 = 1
So 129171-83-1 is a valid CAS Registry Number.

ENANTIOSESELECTIVE SYNTHESIS OF A VERSATILE 2-ISOCEPHEM SYNTHON
Aszodi, Jozsef,Bonnet, Alain,Teutsch, Georges
, p. 1579 - 1586 (2007/10/02)
Enantioselective synthesis of the isocephem synthon 2 has been carried out by assembling 3 building blocks.Cycloaddition of phthalimido acetyl chloride with a chiral imine gave the β-lactam nucleus in 80percent diastereoisomeric excess (d.e.).The elaborat
