Check Digit Verification of cas no

The CAS Registry Mumber 107134-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,1,3 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 107134-90:
(8*1)+(7*0)+(6*7)+(5*1)+(4*3)+(3*4)+(2*9)+(1*0)=97
97 % 10 = 7
So 107134-90-7 is a valid CAS Registry Number.

Syntheses with N-Trimethylsilylheteroarylium Salts: Reactions with Aldehydes, Ketones and Carboxylic Acids. Comparison of Reactivity with Analogous N-Acylheteroarylium Salts

Anders, Ernst,Stankowiak, Achim,Riemer, Roland

, p. 931 - 934 (1987)

N-Trimethylsilylheteroarylium salts 2 can be characterized as efficient silylating reagents for carbonyl compounds (5 or 8) and carbonic acids 11, their reactivity is comparable to that of N-acylheteroarylium salts 1.In some cases (depending on the nature of the substrates), their silylating power can be stronger than the acylating power of comparable salts 1.This will be demonstrated in the case of enolizable examples of 5 and 8.
