113893-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113893-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,8,9 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113893-01:
(8*1)+(7*1)+(6*3)+(5*8)+(4*9)+(3*3)+(2*0)+(1*1)=119
119 % 10 = 9
So 113893-01-9 is a valid CAS Registry Number.

, p. 2052 - 2055 (2007/10/02)
The coupling of chloro or bromo pyrazines and pyridines with areneboronic acids in the presence of palladium(0) catalysts is described.By use of the appropriate catalyst, the coupling of pyridineboronic acids was achieved.A convergent synthesis of the pre
