89471-17-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89471-17-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,7 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89471-17:
(7*8)+(6*9)+(5*4)+(4*7)+(3*1)+(2*1)+(1*7)=170
170 % 10 = 0
So 89471-17-0 is a valid CAS Registry Number.

Sulfur-containing arotinoids, a new class of retinoids
Klaus,Bollag,Huber,Kung
, p. 425 - 429 (2007/10/02)
The synthesis and biological activity of a new class of retinoids with a sulfur containing end group instead of a carboxylic acid, is described. The most active compound, the ethyl sulfone 14 has a 5 times better therapeutic index than retinoic acid. Whil
