1281934-06-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1281934-06-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,1,9,3 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1281934-06:
(9*1)+(8*2)+(7*8)+(6*1)+(5*9)+(4*3)+(3*4)+(2*0)+(1*6)=162
162 % 10 = 2
So 1281934-06-2 is a valid CAS Registry Number.

, p. 1034 - 1039 (2010)
A modular synthetic approach for preparing a family of porphyrin appended 1,3,4-oxadiazoles 9 is described. The porphyrin hydrazides are reacted with aryl aldehydes in presence of Yb(OTf)3 as catalyst to give porphyrin hydrazones 8 which are th
