Check Digit Verification of cas no

The CAS Registry Mumber 1643356-27-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,3,3,5 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1643356-27:
(9*1)+(8*6)+(7*4)+(6*3)+(5*3)+(4*5)+(3*6)+(2*2)+(1*7)=167
167 % 10 = 7
So 1643356-27-7 is a valid CAS Registry Number.

Practical synthesis of natural plant-growth regulator 2-azahypoxanthine, its derivatives, and biotin-labeled probes

Ikeuchi, Kazutada,Fujii, Ryosuke,Sugiyama, Shimpei,Asakawa, Tomohiro,Inai, Makoto,Hamashima, Yoshitaka,Choi, Jae-Hoon,Suzuki, Tomohiro,Kawagishi, Hirokazu,Kan, Toshiyuki

, p. 3813 - 3815 (2014/06/09)

We describe a practical, large-scale synthesis of the "fairy- ring" plant-growth regulator 2-azahypoxanthine (AHX), and its biologically active hydroxyl metabolite (AOH) and riboside derivative (AHXr). AHXr, a biosynthetic intermediate, was synthesized from inosine via a biomimetic route. Biotinylated derivatives of AHX and AHXr were also synthesized as probes for mechanistic studies. This journal is the Partner Organisations 2014.
