Check Digit Verification of cas no
The CAS Registry Mumber 32296-88-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,2,9 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 32296-88:
(7*3)+(6*2)+(5*2)+(4*9)+(3*6)+(2*8)+(1*8)=121
121 % 10 = 1
So 32296-88-1 is a valid CAS Registry Number.

(Trimethylsilyl)ethoxyacetylene, a stable and easy-handling reagent, serves as an excellent dehydrating agent for the synthesis of carboxylic anhydrides and amides from the corresponding carboxylic acids.By means of this reagent, various types of acid-sensitive carboxylic anhydrides and amides were obtained almost in quantative yields.Twenty-two examples of carboxylic anhydrides and 12 examples of amides were presented.
