213382-09-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213382-09-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,3,8 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 213382-09:
(8*2)+(7*1)+(6*3)+(5*3)+(4*8)+(3*2)+(2*0)+(1*9)=103
103 % 10 = 3
So 213382-09-3 is a valid CAS Registry Number.

Synthesis of some new heterocycles derived from arylmethylenemalononitriles
El-Sayed,Khodairy
, p. 3331 - 3343 (1998)
Arylmethylenemalononitriles 1 were treated with halo compounds under phase transfer catalysis (PTC) conditions to yield α-polyfunctional arylmethylene-malononitrile derivatives 2-4. The treatment of compounds 2-4 with hydrazine hydrate gave pyridinones 5,
