154316-32-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154316-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,3,1 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 154316-32:
(8*1)+(7*5)+(6*4)+(5*3)+(4*1)+(3*6)+(2*3)+(1*2)=112
112 % 10 = 2
So 154316-32-2 is a valid CAS Registry Number.

A NEW SYNTHESIS OF 4H-THIOPYRAN-4-THIONES FROM ACETYLENIC β-DIKETONES
Marei, Mohamed Gaber
, p. 101 - 110 (2007/10/02)
2,6-Diaryl-4H-thiopyran-4-thiones have been synthesized in excellent yields by the reaction of 1-aryl-5-phenyl-4-pentyne-1,3-diones with phosphorus pentasulfide in dry pyridine at room temperature and were converted into the corresponding hydrazones and o
