143159-80-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143159-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,1,5 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143159-80:
(8*1)+(7*4)+(6*3)+(5*1)+(4*5)+(3*9)+(2*8)+(1*0)=122
122 % 10 = 2
So 143159-80-2 is a valid CAS Registry Number.

MESOIONIC OXAZOLONES. VI. HYDROLYSIS OF ACYLATED DERIVATIVES
Petride, Horia
, p. 1113 - 1122 (2007/10/03)
Nonplanar acylated mesoionic oxazolones 10-16 underwent hydrolysis at ambient temperature, while their planar analogs 8-9 did it only at 100 deg C. The same trend in reactivity was observed in the case of the monocyclic compounds 34a (planar) and 34b (non
