31140-74-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31140-74-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,4 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 31140-74:
(7*3)+(6*1)+(5*1)+(4*4)+(3*0)+(2*7)+(1*4)=66
66 % 10 = 6
So 31140-74-6 is a valid CAS Registry Number.

Potential mechanism-based tyrosine kinase inhibitors. Part 2. Design and synthesis of peptides containing heterocyclic tyrosine analogues

Andrews, David M.,Gregoriou, Mary,Page, Timothy C. M.,Peach, Josephine M.,Pratt, Andrew J.

, p. 1335 - 1340 (2007/10/02)

The Fmoc derivatives of two homochiral tyrosine analogues, a pyridine N-oxide and a pyridone, have been prepared in high stereochemical purity.Solid-phase synthesis has been used to prepare a decapeptide substrate for the tyrosine kinase domain of epidermal growth factor.Two decapeptides, which incorporate the tyrosine analogues in place of tyrosine, and thereby have the potential to act as mechanism-based inhibitors of epidermal growth factor tyrosine kinase, have been synthesised and found to inhibit the aforementioned kinase.
