142020-64-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142020-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,2 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142020-64:
(8*1)+(7*4)+(6*2)+(5*0)+(4*2)+(3*0)+(2*6)+(1*4)=72
72 % 10 = 2
So 142020-64-2 is a valid CAS Registry Number.

2-λ3-phosphaquinoline
David,Niecke,Nieger
, p. 2335 - 2338 (2007/10/02)
A synthetic route to 2-λ3-phosphachinolines is reported. The reaction of the phosphanetriylammoniumion 1, [PNAr]+, with alkines 2, RCCR', (R=R'=Ph; R=H, R'=Ph), affords the N-protonated derivative phosphachinolinium salts 5, which ca
