Check Digit Verification of cas no
The CAS Registry Mumber 338454-14-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,8,4,5 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 338454-14:
(8*3)+(7*3)+(6*8)+(5*4)+(4*5)+(3*4)+(2*1)+(1*4)=151
151 % 10 = 1
So 338454-14-1 is a valid CAS Registry Number.

Preparation method of nitrogen unsubstituted pyrazole and indazole boric acid
-
Paragraph 0061-0063; 0067-0070, (2020/01/12)
The invention discloses a method for preparing nitrogen unsubstituted pyrazole and indazole boric acid. Nitrogen unsubstituted halogenated pyrazole and a derivative thereof, or nitrogen unsubstitutedhalogenated indazole and a derivative of the nitrogen unsubstituted halogenated indazole react with triisopropylchlorosilane in an organic solvent to generate a triisopropylsilyl protected halogenatedpyrazole or halogenated indazole compound, then a lithium-bromine exchange reaction is carried out with n-butyl lithium, a borate is added to introduce boron atoms, and the nitrogen unsubstituted pyrazole or indazole boric acid is obtained in high yield after hydrolysis.
