Check Digit Verification of cas no
The CAS Registry Mumber 175880-94-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,8,8 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 175880-94:
(8*1)+(7*7)+(6*5)+(5*8)+(4*8)+(3*0)+(2*9)+(1*4)=181
181 % 10 = 1
So 175880-94-1 is a valid CAS Registry Number.

Reactions of 5-Amino-2-isoxazolines and 5-Amino-2-pyrazolines with Phenyl Isothiocyanate
Ershov, A. Yu.
, p. 981 - 983 (2007/10/03)
Treatment of solid 2,4-pentanedione monooxime and monoacetylhydrazone with ammonia and methylamine leads to formation of 5-amino-2-isoxazolines and hitherto unknown 5-amino-2-pyrazolines.These compounds react with phenyl isothiocyanate, yielding N-phenylt
