113977-43-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113977-43-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,9,7 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 113977-43:
(8*1)+(7*1)+(6*3)+(5*9)+(4*7)+(3*7)+(2*4)+(1*3)=138
138 % 10 = 8
So 113977-43-8 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
