131388-03-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131388-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,8 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131388-03:
(8*1)+(7*3)+(6*1)+(5*3)+(4*8)+(3*8)+(2*0)+(1*3)=109
109 % 10 = 9
So 131388-03-9 is a valid CAS Registry Number.

The stereochemistry of organometallic compounds. XLIII* rhodium-catalysed reactions of 2-(alkenyloxy)benzylamines and 2-(N-allyl-N-benzylamino)benzylamine

Campi, Eva M.,Jackson, W. Roy,McCubbin, Quentin J.,Trnacek, Andrew E.

, p. 219 - 230 (2007/10/03)

Reactions of 2-(allyloxy)benzylamines with H2/CO in the presence of rhodium catalysts give 1,3-benzoxazines, and 2-(N-allyl-N-benzylamino)benzylamine gives a quinazoline. These reactions have been shown to involve allylic cleavage followed by regioselective carbonylation at the internal carbon atom as demonstrated by crossover experiments. Reactions of longer chain (alkenyloxy)benzylamines under similar conditions give polymeric material.
