141269-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141269-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,2,6 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 141269-56:
(8*1)+(7*4)+(6*1)+(5*2)+(4*6)+(3*9)+(2*5)+(1*6)=119
119 % 10 = 9
So 141269-56-9 is a valid CAS Registry Number.

, p. 1835 - 1839 (2007/10/02)
Use of diphenyl(2-pyridyl)phosphine instead of triphenylphosphine in the Mitsunobu esterification reaction facilitates isolation of the desired ester.The resulting phosphine oxide is readily removed by a dilute acid wash. 31P n.m.r. investigations of the
