β-1,4-galactosyl transferase, also known as lactose synthase, is an enzyme found in bovine milk that plays a crucial role in the synthesis of lactose, a disaccharide sugar composed of glucose and galactose. This enzyme catalyzes the transfer of a galactose molecule from uridine diphosphate galactose (UDP-Gal) to glucose, forming lactose. Lactose synthase is a bifunctional enzyme, consisting of two subunits: α-lactalbumin and β-1,4-galactosyl transferase. The enzyme is essential for the production of lactose in mammalian milk, providing an energy source for the newborn and promoting the absorption of calcium. In bovine milk, β-1,4-galactosyl transferase is particularly important for the lactose content, which is a key component of milk and dairy products.

Check Digit Verification of cas no

The CAS Registry Mumber 9030-11-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,3 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 9030-11:
(6*9)+(5*0)+(4*3)+(3*0)+(2*1)+(1*1)=69
69 % 10 = 9
So 9030-11-9 is a valid CAS Registry Number.
