357610-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 357610-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,7,6,1 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 357610-25:
(8*3)+(7*5)+(6*7)+(5*6)+(4*1)+(3*0)+(2*2)+(1*5)=144
144 % 10 = 4
So 357610-25-4 is a valid CAS Registry Number.

, p. 6541 - 6544 (2007/10/03)
A general method has been developed for the synthesis of N-tert-butyloxycarbonyl N-carboxyanhydrides from β-amino acids using Vilsmeier complex. These β-UNCA are stable, and the reactivity with different nucleophiles (alcohol, amine, lithium enolate) was studied.
