690652-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 690652-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,6,5 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 690652-89:
(8*6)+(7*9)+(6*0)+(5*6)+(4*5)+(3*2)+(2*8)+(1*9)=192
192 % 10 = 2
So 690652-89-2 is a valid CAS Registry Number.

2,4-Dinitrophenol as an activating reagent in a facile preparation of cyclic phosphate triesters
Amigues, Eric J.,Migaud, Marie E.
, p. 1001 - 1004 (2007/10/03)
2,4-Dinitrophenol was employed with benzyloxy-bis-(diisopropylamino) phosphine to synthesise the cyclic phosphate derivatives of a series of alkane diols (HO-(CH2)n-OH, n=2-6) in good isolated yields. Tetrazole and DNP were compared
