6172-07-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6172-07-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,7 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6172-07:
(6*6)+(5*1)+(4*7)+(3*2)+(2*0)+(1*7)=82
82 % 10 = 2
So 6172-07-2 is a valid CAS Registry Number.

Teulade, Marie-Paule,Savignac, Philippe
, p. 125 - 136 (2007/10/02)
Preparation of 1-formyl 1,1-dialkylmethylphosphonates is described.A carbanionic route is provided by the condensation of α-lithio α,α-disubstituted methylphosphonates with ethylformate whereas a carbocationic route provided by the acid catalyzed rearrang
