124357-48-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124357-48-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,3,5 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 124357-48:
(8*1)+(7*2)+(6*4)+(5*3)+(4*5)+(3*7)+(2*4)+(1*8)=118
118 % 10 = 8
So 124357-48-8 is a valid CAS Registry Number.

ALKYLATION OF ISOLATED THIAMIN YLIDE
Sugimoto, Hirohiko,Hirai, Kentaro
, p. 877 - 880 (2007/10/02)
Alkylation of isolated thiamin ylide (TY, 3) in EtOH under the neutral conditions afforded thiamin (TH+Cl-, 1) and the alkylated yellow form 4, which provides direct chemical evidence for the disproportionation of thiamin ylide into the ion pair of the yellow form (TH+YF-, 6) in a protic solvent.
