Check Digit Verification of cas no
The CAS Registry Mumber 172168-03-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,1,6 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 172168-03:
(8*1)+(7*7)+(6*2)+(5*1)+(4*6)+(3*8)+(2*0)+(1*3)=125
125 % 10 = 5
So 172168-03-5 is a valid CAS Registry Number.

Rapid and efficient C(4)-alkylation of 4-alkyloxazol-5(4H)-ones has been achieved by the utilization of BEMP as base. 4,4-Dialkyloxazol-5(4H)-ones, which can easily be hydrolyzed into free α,α-dialkyl-α-amino acids, were obtained in high yields (up to 99%
