135338-96-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135338-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,3 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 135338-96:
(8*1)+(7*3)+(6*5)+(5*3)+(4*3)+(3*8)+(2*9)+(1*6)=134
134 % 10 = 4
So 135338-96-4 is a valid CAS Registry Number.

The 1,3-dipolar cycloadditions of nitrile oxides and nitrile imines to alkyl dicyanoacetates
Neidlein, Richard,Sui, Zhihua
, p. 501 - 507 (2007/10/02)
The readily available alkyl dicyanoacetates 1 reacted with the 1,3-dipolar reagents arenecarbonitrile oxides 2′ and arenecarbonitrile imines 5′ to afford 1,2,4-oxadiazol and 1,2,4-triazol derivatives. The arenecarbonitrile oxides 2′ with electron-donating
