Check Digit Verification of cas no
The CAS Registry Mumber 4188-69-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,8 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4188-69:
(6*4)+(5*1)+(4*8)+(3*8)+(2*6)+(1*9)=106
106 % 10 = 6
So 4188-69-6 is a valid CAS Registry Number.

In situ NMR study of the rhodium(I)-catalyzed hydrogenation of the allene 1-methoxy-propa-1,2-diene using parahydrogen
Harthun,Bargon,Selke
, p. 7755 - 7758 (2007/10/02)
The homogeneous hydrogenation of 1-methoxy-propa-1,2-diene was investigated via in situ 1H-NMR spectroscopy using different rhodium(I) catalysts and parahydrogen (p-H2). The detected polarization signals allow the determination of the hydrogenation products due to their characteristic patterns.
