17487-80-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17487-80-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,4,8 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17487-80:
(7*1)+(6*7)+(5*4)+(4*8)+(3*7)+(2*8)+(1*0)=138
138 % 10 = 8
So 17487-80-8 is a valid CAS Registry Number.

Novel syntheses of spiropyran photochromatic compounds using ultrasound
Torres,Vazquez,Gonzalez
, p. 105 - 110 (2007/10/02)
Photochromatic derivatives 1,3,3-trimethylindoline-2-spiro-2'-benzopyran, were synthesized using ultrasound as energy source (55 watt), reaction times are between 10 to 20 min, obtaining higher or slightly lower yield than the conventional reported methods.
