155164-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155164-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,1,6 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 155164-66:
(8*1)+(7*5)+(6*5)+(5*1)+(4*6)+(3*4)+(2*6)+(1*6)=132
132 % 10 = 2
So 155164-66-2 is a valid CAS Registry Number.

2-Acylpyridazin-3-ones: Novel mild and chemoselective acylating agents for amines
Kang, Young-Jin,Chung, Hyun-A,Kim, Jeum-Jong,Yoon, Yong-Jin
, p. 733 - 738 (2007/10/03)
2-Acyl-4,5-dichloropyridazin-3-ones served as excellent novel N-acylating reagents for amines under neutral conditions in organic solvent. They are convenient, chemoselective and easy to handle stable N-acylating reagents of amines.
