127357-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127357-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,3,5 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 127357-53:
(8*1)+(7*2)+(6*7)+(5*3)+(4*5)+(3*7)+(2*5)+(1*3)=133
133 % 10 = 3
So 127357-53-3 is a valid CAS Registry Number.

General Synthesis of β,γ-Alkynylglycine Derivatives
Williams, Robert M.,Aldous, David J.,Aldous, Suzanne C.
, p. 4657 - 4663 (2007/10/02)
The coupling of α-haloglycinates 8 with alkynyltin reagents produces the fully protected β,γ-alkynylglycines 9.Subsequent deprotection of the amino or carboxyl groups generates differentially protected β,γ-alkynylglycine derivatives 10-14.The free amino a
