300397-43-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 300397-43-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,0,3,9 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 300397-43:
(8*3)+(7*0)+(6*0)+(5*3)+(4*9)+(3*7)+(2*4)+(1*3)=107
107 % 10 = 7
So 300397-43-7 is a valid CAS Registry Number.

Condensation of Carboxylic Acids with Non-Nucleophilic N-Heterocycles and Anilides Using Boc2O
Umehara, Atsushi,Ueda, Hirofumi,Tokuyama, Hidetoshi
, p. 11444 - 11453 (2016)
A novel condensation reaction of carboxylic acids with various non-nucleophilic N-heterocycles and anilides was developed. The reaction proceeds in the presence of di-tert-butyl dicarbonate (Boc2O), catalytic 4-(dimethylamino)pyridine (DMAP), a
