99779-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99779-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,7 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99779-72:
(7*9)+(6*9)+(5*7)+(4*7)+(3*9)+(2*7)+(1*2)=223
223 % 10 = 3
So 99779-72-3 is a valid CAS Registry Number.

, p. 685 - 688 (2007/10/02)
Arylmalononitriles were prepared from the corresponding benzoyl chlorides by three reaction steps.Treatment of the starting substances with cyanotrimethylsilane in the presence of pyridine gave dicyanotrimethylsiloxymethylbenzenes, which were transformed
