104662-65-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104662-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,6 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104662-65:
(8*1)+(7*0)+(6*4)+(5*6)+(4*6)+(3*2)+(2*6)+(1*5)=109
109 % 10 = 9
So 104662-65-9 is a valid CAS Registry Number.

, p. 979 - 981 (2007/10/02)
Two new routes have been developed for the synthesis of 2,5,6-triaryl-4H-1,3,4-oxadiazines (IV).The first route involves condensation of benzoin (I) with various aromatic acid hydrazides (II) followed by cyclisation of the resulting schiffs bases (III) wi
