89155-03-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89155-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,5 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89155-03:
(7*8)+(6*9)+(5*1)+(4*5)+(3*5)+(2*0)+(1*3)=153
153 % 10 = 3
So 89155-03-3 is a valid CAS Registry Number.

SOME TRANSFORMATIONS OF 2-(2-HYDROXY-3-CHLOROPROPYLTHIO)BENZOTHIAZOLE
Sabirov, K.,Rozhkova, N. K.
, p. 1173 - 1174 (2007/10/02)
The reaction of phenyl isocyanate and acetic anhydride with 2-(2-hydroxy-3-chloropropylthio)benzothiazole was studied.At 140 deg C, this benzothiazole cyclizes with the formation of quarternary salts which readily reacts with hydrazine and alkali.
