180721-04-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 180721-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,7,2 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 180721-04:
(8*1)+(7*8)+(6*0)+(5*7)+(4*2)+(3*1)+(2*0)+(1*4)=114
114 % 10 = 4
So 180721-04-4 is a valid CAS Registry Number.

A DNA-templated aldol reaction as a model for the formation of pentose sugars in the RNA world
Oberhuber, Michael,Joyce, Gerald F.
, p. 7580 - 7583 (2005)
Sugar on a stick: A DNA template can bind two complementary oligonucleotides, one derivatized with glyceraldehyde (blue) and the other with glycolaldehyde (red), resulting in a cross-aldol reaction that forms pentose sugars. This reaction system serves as
