Check Digit Verification of cas no
The CAS Registry Mumber 33993-24-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,9 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33993-24:
(7*3)+(6*3)+(5*9)+(4*9)+(3*3)+(2*2)+(1*4)=137
137 % 10 = 7
So 33993-24-7 is a valid CAS Registry Number.

, p. 5322 - 5323 (2008/12/22)
The high yielding synthesis of symmetrical carboxylic anhydrides from acid chlorides mediated by zinc dust in the presence of dimethylformamide is presented. A mechanism involving the reductive insertion of zinc(0) into the C-Cl bond of a Vilsmeier-type iminium intermediate as the crucial step is also proposed.
