345940-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 345940-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,5,9,4 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 345940-30:
(8*3)+(7*4)+(6*5)+(5*9)+(4*4)+(3*0)+(2*3)+(1*0)=149
149 % 10 = 9
So 345940-30-9 is a valid CAS Registry Number.

SYNTHESIS OF TRISUBSTITUTED 4H-1,2,4-OXADIAZINES
Zen, Shonosuke,Harada, Kazuho
, p. 1711 - 1714 (2007/10/02)
The derivatives of 4H-1,2,4-oxadiazine, a new class of six-membered heterocycles, were synthesized through the reactions of β-diketones with aliphatic nitro compounds and acetyl chloride, and also of azirines with nitrile oxides.A reaction mechanism is pr
