Check Digit Verification of cas no
The CAS Registry Mumber 105907-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,9,0 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 105907-18:
(8*1)+(7*0)+(6*5)+(5*9)+(4*0)+(3*7)+(2*1)+(1*8)=114
114 % 10 = 4
So 105907-18-4 is a valid CAS Registry Number.

A new approach to the synthesis of β-amino acids
Della Rosa, Claudia,Gil, Salvador,Rodriguez, Pablo,Parra, Margarita
, p. 3092 - 3098 (2008/02/08)
A detailed study of the addition of the dianions of carboxylic acids to isocyanates is presented. The use of sub-stoichiometric amounts of the amine in the generation of the dianion leads to an optimized process, which prevents the formation of urea deriv
