Check Digit Verification of cas no

The CAS Registry Mumber 52776-35-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,7,7 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 52776-35:
(7*5)+(6*2)+(5*7)+(4*7)+(3*6)+(2*3)+(1*5)=139
139 % 10 = 9
So 52776-35-9 is a valid CAS Registry Number.

Regioselective synthesis of (trifluoromethyl)-β-chloroenones

Alvernhe, Gerard,Bensadat, Abdelkader,Ghobsi, Abdelkader,Laurent, Andre,Laurent, Eliane

, p. 169 - 172 (1997)

The regioselectivity of the conversion of 1,3-diketones into β-chloroenones can be changed by the appropriate choice of the reagent: reaction with "Vilsmeier's reagent" prepared from POCl3 and dimethylformamide or treatment of the diketone with the oxalyl chloride in the presence of dimethylformamide.
