Check Digit Verification of cas no

The CAS Registry Mumber 104292-88-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,9 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 104292-88:
(8*1)+(7*0)+(6*4)+(5*2)+(4*9)+(3*2)+(2*8)+(1*8)=108

Facile and Efficient Syntheses of Carboxylic Anhydrides and Amides Using (Trimethylsilyl)ethoxyacetylene

Kita, Yasuyuki,Akai, Shuji,Ajimura, Naomi,Yoshigi, Mayumi,Tsugoshi, Teruhisa,et al.

, p. 4150 - 4158 (2007/10/02)

(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.
