Check Digit Verification of cas no
The CAS Registry Mumber 34867-74-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,6 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 34867-74:
(7*3)+(6*4)+(5*8)+(4*6)+(3*7)+(2*7)+(1*4)=148
148 % 10 = 8
So 34867-74-8 is a valid CAS Registry Number.

ONE-POT SYNTHESIS OF 2,2,4-TRICHLOROBUTANAL FROM TETRAHYDROFURAN
Buyck, Laurent De,Menke, Niclas,Louagie, Jan
, p. 187 - 189 (2007/10/02)
Tetrahydrofuran was converted to 2,2,4-trichlorobutanal (1) in 60-73percent overall yield by isomerisation of intermediate 2,3,3-trichlorotetrahydrofuran (2) in the presence of 4-6percent (w:w) of aluminium trichloride at 100-140 deg C for 40-60 min.Zinc chloride and titanium tetrachloride were less effective as catalysts, while hydrogen chloride and paratoluenesulfonic acid were ineffective.
