Check Digit Verification of cas no

The CAS Registry Mumber 1352721-81-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,7,2 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1352721-81:
(9*1)+(8*3)+(7*5)+(6*2)+(5*7)+(4*2)+(3*1)+(2*8)+(1*1)=143
143 % 10 = 3
So 1352721-81-3 is a valid CAS Registry Number.

One-pot synthesis of α-amino acids from CO2 using a bismetal reagent with Si-B bond

Mita, Tsuyoshi,Chen, Jianyang,Sugawara, Masumi,Sato, Yoshihiro

, p. 6202 - 6205 (2013/02/23)

In the presence of 1.1 equiv of PhMe2Si-Bpin, 5 equiv of CsF, and 20 mol % of TsOH·H2O, precursors of N-Boc-imines can be converted into the corresponding α-aryl or α-alkenyl glycine derivatives under gaseous CO2 in moderate-to-high yields with a single operation. α-Isobutenyl glycine thus obtained can be further derivatized into various types of α-amino acids including N-Boc-leucine, serine, and glycine derivatives in short steps.
