18515-19-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18515-19-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,5,1 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18515-19:
(7*1)+(6*8)+(5*5)+(4*1)+(3*5)+(2*1)+(1*9)=110
110 % 10 = 0
So 18515-19-0 is a valid CAS Registry Number.

Comparative Reactivity of Substituted 4-Nitrobenzylidene Dichlorides with Alkali
Goh, Swee Hock,Kam, Toh Seok
, p. 423 - 426 (2007/10/02)
A comparative study of the reactions of substituted 4-nitrobenzylidene dichlorides ArCHCl2 (Ar = 3-Cl-4-NO2C6H3, 2-Cl-4-NO2C6H3, 4-NO2C6H4, 3,5-Me2-4-NO2C6H2, and 2-Me-4-NO2C6H3) with aqueous alcoholic alkali shows that chlorine substitution enhances the
