Check Digit Verification of cas no

The CAS Registry Mumber 223693-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,6,9 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 223693-28:
(8*2)+(7*2)+(6*3)+(5*6)+(4*9)+(3*3)+(2*2)+(1*8)=135
135 % 10 = 5
So 223693-28-5 is a valid CAS Registry Number.

Stereocontrolled elaboration of natural (-)-polycavernoside A, a powerfully toxic metabolite of the red alga Polycavernosa tsudai

Paquette, Leo A.,Barriault, Louis,Pissarnitski, Dmitri,Johnston, Jeffrey N.

, p. 619 - 631 (2007/10/03)

A stereoselective total synthesis of natural levorotatory polycavernoside A (1) has been achieved. Initial investigations produced the properly activated disaccharide unit 18b via the conjoining of building blocks originating from L-fucose and D-xylose. T
