41902-21-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 41902-21-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,9,0 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 41902-21:
(7*4)+(6*1)+(5*9)+(4*0)+(3*2)+(2*2)+(1*1)=90
90 % 10 = 0
So 41902-21-0 is a valid CAS Registry Number.

Synthese et etude chimique preliminaire des pentadienyl-2,4-phosphines
Santini, Catherine C.,Mathey, Francois
, p. 21 - 25 (2007/10/02)
A penta-2,4-dienylphosphine oxide is easly obtained by reaction of methylmagnesium iodide with 1-oxa-2-phosphacycloheta-4,6-diene followed by two more intermediate steps.The corresponding phosphine may be obtained either by trichlorosilane reduction of th
