Check Digit Verification of cas no

The CAS Registry Mumber 190186-36-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,1,8 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 190186-36:
(8*1)+(7*9)+(6*0)+(5*1)+(4*8)+(3*6)+(2*3)+(1*6)=138
138 % 10 = 8
So 190186-36-8 is a valid CAS Registry Number.

Fast hydrazone reactants: Electronic and acid/base effects strongly influence rate at biological pH

Kool, Eric T.,Park, Do-Hyoung,Crisalli, Pete

supporting information, p. 17663 - 17666 (2014/01/06)

Kinetics studies with structurally varied aldehydes and ketones in aqueous buffer at pH 7.4 reveal that carbonyl compounds with neighboring acid/base groups form hydrazones at accelerated rates. Similarly, tests of a hydrazine with a neighboring carboxylic acid group show that it also reacts at an accelerated rate. Rate constants for the fastest carbonyl/hydrazine combinations are 2-20 M-1 s-1, which is faster than recent strain-promoted cycloaddition reactions.

Preparation of 2-deoxyaldoses from aldose phenylhydrazones

Jorgensen, Christel,Pedersen, Christian

, p. 307 - 310 (2007/10/03)

Acetylation of D-mannose phenylhydrazone gives acetylated D-arabino-1-phenyl-azo-1-(E)-hexene. Subsequent reduction with sodium borohydride produces 2-deoxy-D-arabino-hexose phenylhydrazone which, on hydrolysis, gives 2-deoxy-D-arabino-hexose. By a similar procedure 2-deoxy-D-lyxo-hexose, 2,6-dideoxy-L-arabino-hexose, and 2-deoxy-D-erythropentose can be prepared from D-galactose, L-rhamnose, and D-arabinose, respectively.
