131471-15-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131471-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,7 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131471-15:
(8*1)+(7*3)+(6*1)+(5*4)+(4*7)+(3*1)+(2*1)+(1*5)=93
93 % 10 = 3
So 131471-15-3 is a valid CAS Registry Number.

THE INTRAMOLECULAR CYCLOADDITION REACTION OF AZOMETHINE YLIDES GENERATED FROM BENZYLIC N-OXIDES
Roussi, Georges
, p. 1445 - 1450 (2007/10/02)
Benzylic azomethine ylides (Y) generated by deprotonation of the corresponding tertiary amine N-oxides (1a, 1b, 4) react intramoleculary with the suitably positioned unactivated double bond to yield the corresponding fused membered pyrrolidines (2a, 2b, 5
