Check Digit Verification of cas no

The CAS Registry Mumber 146726-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,7,2 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 146726-33:
(8*1)+(7*4)+(6*6)+(5*7)+(4*2)+(3*6)+(2*3)+(1*3)=142
142 % 10 = 2
So 146726-33-2 is a valid CAS Registry Number.

Fast preparation of dihydrocyclocitral from citronellal under solventless microwave irradiation

Nhuan, Ngoc Doan,Thach, Ngoc Le,Poul, Erik Hansen,Duus, Fritz

, p. 6749 - 6751 (2007/10/03)

Dihydrocyclocitral, a useful reagent in organic synthesis, has been synthesized in high yield and with high stereoselectivity from citronellal under microwave irradiation in two steps, involving acetic anhydride under base catalysis, then p-toluenesulfonic acid adsorbed on silica gel under solventless conditions (80% yield, reaction time 22 min).
