110840-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 110840-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,8,4 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 110840-40:
(8*1)+(7*1)+(6*0)+(5*8)+(4*4)+(3*0)+(2*4)+(1*0)=79
79 % 10 = 9
So 110840-40-9 is a valid CAS Registry Number.

SYN-SELECTIVE ADDITIONS OF ACETYLIDE ANIONS TO α-ALKOXYALDEHYDES
Mead, Keith T.
, p. 1019 - 1022 (2007/10/02)
1-Alkynyl zinc bromide reagents were found to add to α-benzyloxyaldehydes in ether solvent with good to excellent syn selectivity.A chelate model is proposed to explain these results.
