84538-94-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84538-94-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,3 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84538-94:
(7*8)+(6*4)+(5*5)+(4*3)+(3*8)+(2*9)+(1*4)=163
163 % 10 = 3
So 84538-94-3 is a valid CAS Registry Number.

Paragraph 0030-0032; 0040, (2018/06/26)

PROBLEM TO BE SOLVED: To provide a production method of an allyl compound of carrying out the dehydration allylation of a substrate having S, C or N which is a nucleophilic atom, especially S under the presence of a catalyst system consisting of a catalyst precursor having a specific structure and a specific ligand. SOLUTION: The production method of allyl compounds comprises as follow. A catalyst precursor chosen from Formula (1) and Formula (2) and a ligand are mixed, or a catalyst precursor, an allyl alcohol, and a ligand are mixed, then allyl alcohols and a substrate are blended and made to react. The ligand is quinaldic acid or picolinic acid, and the substrate is thiols, thiocarboxylic acids or the like. [Ru(C5H5)(CH3CN)3]PF6(1). [Ru[C5(CH3)5](CH3CN)3]PF6(2). COPYRIGHT: (C)2012,JPOandINPIT
