9001-98-3 Usage
Chemical Properties
Yellowish-white powder or as yellow
grains or scales; characteristic slightly salty taste;
peculiar odor. Slightly hygroscopic; partially solu-
ble in water and dilute alcohol.
Uses
Different sources of media describe the Uses of 9001-98-3 differently. You can refer to the following data:
1. Rennin, also known as chymosin, is a milkclotting acid proteinase produced in the stomach of a calf. It is used in cheesemaking and to study neonatal gastric digestion .
2. Rennet (a dried extract contg rennin) is used in the manufacture of cheese and rennet casein, also sold retail for the making of junket or rennet custards.
Definition
A digestive enzyme secreted by the
glands of the stomach and causes curdling of milk.
It has the power of coagulating 25,000 times its own
weight of milk.
Biochem/physiol Actions
Rennin, a 323 amino acid chain, is secreted as an inactive precursor which is then converted into an active enzyme through limited proteolysis. It cleaves the peptide bond between phenylalanine and methionine in K-Casein.
Check Digit Verification of cas no
The CAS Registry Mumber 9001-98-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 9001-98:
(6*9)+(5*0)+(4*0)+(3*1)+(2*9)+(1*8)=83
83 % 10 = 3
So 9001-98-3 is a valid CAS Registry Number.
