823-74-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 823-74-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 823-74:
(5*8)+(4*2)+(3*3)+(2*7)+(1*4)=75
75 % 10 = 5
So 823-74-5 is a valid CAS Registry Number.

REACTION OF NUCLEOPHILES WITH ELECTRON ACCEPTORS BY SN2 OR SINGLE ELECTRON TRANSFER (S.E.T.) MECHANISMS: THIOLATES AND 2-HALOMETHYL-5-NITROFURANS.
Beadle, Charles D.,Bowman, W. Russell,Prousek, Josef
, p. 4979 - 4982 (2007/10/02)
Thiolates react with 2-halomethyl-5-nitrofurans to yield 5-nitrofurfuryl sulphides by a SN2(C) mechanism, and disulphides and 2-methyl-5-nitrofuran by a SN2(X) mechanism.
