Check Digit Verification of cas no
The CAS Registry Mumber 33232-06-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,3 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 33232-06:
(7*3)+(6*3)+(5*2)+(4*3)+(3*2)+(2*0)+(1*6)=73
73 % 10 = 3
So 33232-06-3 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.
