Check Digit Verification of cas no
The CAS Registry Mumber 16639-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,3 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16639-19:
(7*1)+(6*6)+(5*6)+(4*3)+(3*9)+(2*1)+(1*9)=123
123 % 10 = 3
So 16639-19-3 is a valid CAS Registry Number.

Convenient Synthesis of Biologically Important Retinoids
Biesalski, Hans-K.,Doepner, Gudrun,Kunz, Horst,Paust, Joachim,John, Michael
, p. 717 - 720 (2007/10/02)
The toxic and teratogenic effects caused by the highly biologically active (all-E)-retinoic acid and its derivatives prompted us to synthesize a number of retinoids.We developed synthetic approaches to (all-E)-retinyl-β-D-glucuronide 3, methyl (retinoyl β
