104891-78-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104891-78-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,9 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 104891-78:
(8*1)+(7*0)+(6*4)+(5*8)+(4*9)+(3*1)+(2*7)+(1*8)=133
133 % 10 = 3
So 104891-78-3 is a valid CAS Registry Number.

HORNER-WITTIG REACTIONS USING DIBENZOPHOSPHOLE OXIDES: STEREOCHEMICALLY CONTROLLED REDUCTION OF KETONES
Elliott, Jason,Warren, Stuart
, p. 645 - 648 (2007/10/02)
Reduction of ketones having an α-dibenzophosphole-5-oxide group with NaBH4, L-Selectride, or Superhydride gives threo Horner-Wittig intermediates and hence E-alkenes, while NaBH4/CeCl3 gives erythro intermediates and hence Z-alkenes.
