190730-97-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 190730-97-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,7,3 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 190730-97:
(8*1)+(7*9)+(6*0)+(5*7)+(4*3)+(3*0)+(2*9)+(1*7)=143
143 % 10 = 3
So 190730-97-3 is a valid CAS Registry Number.

Transition-metal-substituted acyl phosphanes and phosphaalkenes. 32. Transformation of an FeP=C unit of a phosphaalkene into a FeP=C-N-N=C moiety by chain extension through insertion of the 1,3-dipole (-N-N(Ar)-CH+) of sydnones

, p. 2958 - 2962 (2008/10/08)

The metallophosphaalkene (η5-C5Me5)(CO)2FeP=C(NMe 2)2 (1) underwent reaction with sydnones 3-aryl-NNOC(O)CH (aryl = C6H5 (2a), 4-FC6H4 (2b), 4-ClC6H4 (2c), 4-BrC6H4 (2d)) to afford the novel ferriophosphaalkenes (η5-C5Me5)(CO) 2FeP=CHN(aryl)N=C(NMe2)2 (3a-d). Compound 3a forms the [2 + 2] phosphetanyl cycloadduct 4a with dimethyl fumarate. The molecular structure of 3a was determined by single-crystal X-ray diffraction.
