478653-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 478653-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,8,6,5 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 478653-77:
(8*4)+(7*7)+(6*8)+(5*6)+(4*5)+(3*3)+(2*7)+(1*7)=209
209 % 10 = 9
So 478653-77-9 is a valid CAS Registry Number.

N-Alkylation of tosylhydrazones in the presence of triphenylphosphine
Kong, Yuanfang,Zhang, Wen,Tang, Meng,Wang, Haiming
, p. 7487 - 7491 (2013/08/23)
An efficient N-alkylation reaction of tosylhydrazones was developed in the presence of triphenylphosphine; triphenylphosphine played a key role in the transformation. A range of N-alkylated tosylhydrazones were prepared in good to high yields.
