89237-16-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89237-16-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,3 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 89237-16:
(7*8)+(6*9)+(5*2)+(4*3)+(3*7)+(2*1)+(1*6)=161
161 % 10 = 1
So 89237-16-1 is a valid CAS Registry Number.

REACTIONS OF CONJUGATED PHENYLAZOALKENES WITH ANIONIC REAGENTS-5. ANTI-PHENYLHYDRAZONE DERIVATIVES
Bozzini, Silvano,Gratton, Sergio,Lisini, Adriana,Risaliti, Amerigo
, p. 3409 - 3414 (2007/10/02)
Conjugated phenylazoalkenes add anionic reagents to give 2-substituted anti-phenylhydrazones, as demonstrated by (1)H NMR spectroscopy and, in some cases, by comparison with authentic samples.
