93554-03-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93554-03-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,5,5 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 93554-03:
(7*9)+(6*3)+(5*5)+(4*5)+(3*4)+(2*0)+(1*3)=141
141 % 10 = 1
So 93554-03-1 is a valid CAS Registry Number.

C-PHOSPHINOSUBSTITUIERTE PHOSPHAALKENE UND EIN ERSTES CARBODIPHOSPHAN
Karsch, Hans H.,Koehler, Frank H.,Reisacher, Hans-Ulrich
, p. 3687 - 3690 (2007/10/02)
A series of novel phosphoalkenes, Yosh-P=CH-P(X)R (Yosh = 2,4,6-t-Bu3C6H2) has been prepared, as well as the first stable carbodiphosphane, Yosh-P=C=P-Yosh, which has been characterized by elemental analysis, NMR and mass spectroscopy.
