214971-11-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 214971-11-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,9,7 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 214971-11:
(8*2)+(7*1)+(6*4)+(5*9)+(4*7)+(3*1)+(2*1)+(1*1)=126
126 % 10 = 6
So 214971-11-6 is a valid CAS Registry Number.

A facile synthesis of acid anhydrides
Dubey,Kumar, R. Vinod
, p. 1 - 3 (2007/10/03)
A facile synthesis of symmetric and unsymmetric acid anhydrides using phase-transfer catalysis is described. By this method different types of anhydrides can be obtained in high yields under mild conditions even on microscale levels.
