35228-40-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 35228-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,2,2 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 35228-40:
(7*3)+(6*5)+(5*2)+(4*2)+(3*8)+(2*4)+(1*0)=101
101 % 10 = 1
So 35228-40-1 is a valid CAS Registry Number.

Lewis Base-Boryl Radicals Enabled the Desulfurizative Reduction and Annulation of Thioamides

supporting information, p. 24 - 27 (2018/01/17)

A new protocol for radical transformations of thioamides promoted by Lewis base-boryl radicals is reported. The desulfurizative reduction to access organic amines was enabled utilizing 4-dimethylaminopyridine-BH3 as the boryl radical precursor and PhSH as the polarity reversal catalyst. Alternatively, the chain process for unsaturated thioamides was switched to an annulation reaction using N-heterocyclic carbene-BH3 as the boryl radical precursor and sterically bulky Ph3CSH as the catalyst, allowing for the construction of N-heterocyclic and carbocyclic skeletons.
