677341-19-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 677341-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,7,3,4 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 677341-19:
(8*6)+(7*7)+(6*7)+(5*3)+(4*4)+(3*1)+(2*1)+(1*9)=184
184 % 10 = 4
So 677341-19-4 is a valid CAS Registry Number.

Ring Opening Reactions of N-Alkyl Oxazolidinones with Organolithium Reagents
Jones, Simon,Norton, Helen C.
, p. 338 - 340 (2004)
Addition of primary, secondary and aryl organolithium reagents to N-methyl and N-benzyl oxazolidin-2-ones give N-acyl amino alcohols in 30-93% yields. Application to the synthesis of an imidazoyl oxazoline is demonstrated.
