Valyl-valine, also known as valine-valine or diketopiperazine (DKP), is a cyclic dipeptide formed by the condensation of two valine amino acid residues. In this structure, the amino group of one valine molecule reacts with the carboxyl group of another valine molecule, resulting in the formation of a peptide bond and a cyclic structure. Valyl-valine is a white crystalline solid that is insoluble in water and has a molecular weight of 237.3 g/mol. It is found in various food products, such as aged cheese, roasted coffee, and soy sauce, and is known to contribute to the taste and aroma of these products. Additionally, valyl-valine has been studied for its potential biological activities, including antioxidant and anti-inflammatory properties, although more research is needed to fully understand its effects on human health.

Check Digit Verification of cas no

The CAS Registry Mumber 3918-93-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,1 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3918-93:
(6*3)+(5*9)+(4*1)+(3*8)+(2*9)+(1*3)=112
112 % 10 = 2
So 3918-93-2 is a valid CAS Registry Number.
