Check Digit Verification of cas no

The CAS Registry Mumber 1430220-99-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,0,2,2 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1430220-99:
(9*1)+(8*4)+(7*3)+(6*0)+(5*2)+(4*2)+(3*0)+(2*9)+(1*9)=107
107 % 10 = 7
So 1430220-99-7 is a valid CAS Registry Number.

Direct synthesis of amides from carboxylic acids and amines using B(OCH2CF3)3

Lanigan, Rachel M.,Starkov, Pavel,Sheppard, Tom D.

, p. 4512 - 4523 (2013/06/05)

B(OCH2CF3)3, prepared from readily available B2O3 and 2,2,2-trifluoroethanol, is as an effective reagent for the direct amidation of a variety of carboxylic acids with a broad range of amines. In most cases, the amide products can be purified by a simple filtration procedure using commercially available resins, with no need for aqueous workup or chromatography. The amidation of N-protected amino acids with both primary and secondary amines proceeds effectively, with very low levels of racemization. B(OCH2CF3)3 can also be used for the formylation of a range of amines in good to excellent yield, via transamidation of dimethylformamide.
