21650-83-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21650-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,5 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21650-83:
(7*2)+(6*1)+(5*6)+(4*5)+(3*0)+(2*8)+(1*3)=89
89 % 10 = 9
So 21650-83-9 is a valid CAS Registry Number.

A practical solution for aqueous reactions of water-insoluble high-melting-point organic substrates

Cui, Xiaoxue,Li, Bo,Liu, Tianzhen,Li, Chunbao

supporting information; experimental part, p. 668 - 672 (2012/06/01)

A practical solution to the problem of performing aqueous reactions for very sparingly soluble high-melting-point (VSSHMP) organic substrates has been developed, which entails mechanically stirring a mixture of the substrate, the corresponding reagent(s), water, catalytic Aliquat 336 and sand. When the melting points of the substrates which include steroids, ketones, aldehydes, aromatics and alkaloids are around 200 °C, the reactions can be performed at 20 °C. The substrate solubility can be as low as 1 × 10-10 mol L-1. The Royal Society of Chemistry 2012.
