144809-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144809-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,0 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144809-99:
(8*1)+(7*4)+(6*4)+(5*8)+(4*0)+(3*9)+(2*9)+(1*9)=154
154 % 10 = 4
So 144809-99-4 is a valid CAS Registry Number.

, p. 919 - 920 (2007/10/02)
Michael-type addition of N-aryldithiocarbamic acids 2a-c to 4-arylidene-5-oxazolones 1a-c followed by ring transformation of the resulting Michael adducts 3a-i yielded new 5-acylamino-3,6-diarylperhydro-2-thioxo-1,3-thiazin-4-ones 4a-i in one pot.
