102276-26-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102276-26-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,2,7 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 102276-26:
(8*1)+(7*0)+(6*2)+(5*2)+(4*7)+(3*6)+(2*2)+(1*6)=86
86 % 10 = 6
So 102276-26-6 is a valid CAS Registry Number.

DIASTEREOSELECTIVE β-ELIMINATION. SYNTHESIS OF CHIRAL ALKOXY-ALLENES
Alexakis, A.,Mangeney, P.,Normant, J. F.
, p. 4197 - 4200 (1985)
Chiral alkoxy-allenes are obtained by reaction of chiral acetylenic acetals with Grignard regents in the presence of catalytic amount of copper salt.The crucial step is a highly diastereoselective β-elimination reaction of the transient alkenyl organometa
