1019657-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1019657-20-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,9,6,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1019657-20:
(9*1)+(8*0)+(7*1)+(6*9)+(5*6)+(4*5)+(3*7)+(2*2)+(1*0)=145
145 % 10 = 5
So 1019657-20-5 is a valid CAS Registry Number.

Fluorogenic imines for fluorescent detection of Mannich-type reactions of phenols in water
Guo, Hai-Ming,Minakawa, Maki,Tanaka, Fujie
, p. 3964 - 3966 (2008/09/19)
(Chemical Equation Presented) Fluorogenic imines and their precursor amines that can be used for fluorescent visualization of Mannich-type reactions of phenols in aqueous buffers have been developed. The precursor amines are aniline derivatives that are c
