Check Digit Verification of cas no

The CAS Registry Mumber 1310721-40-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,0,7,2 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1310721-40:
(9*1)+(8*3)+(7*1)+(6*0)+(5*7)+(4*2)+(3*1)+(2*4)+(1*0)=94
94 % 10 = 4
So 1310721-40-4 is a valid CAS Registry Number.

Noteworthy observations accompanying synthesis of the apoptolidin disaccharide

Srinivasarao, Madduri,Park, Taesik,Chen, Yuzhong,Fuchs, Philip L.

, p. 5858 - 5860 (2011/07/08)

A stereoselective synthesis of the apoptolidin disaccharide is reported. The key chemistry features a new transformation utilizing a highly selective tetramethylalkoxyalanate[v]-directed syn-methylation of a vinylogous ester, isolation of a hydrate of a 2-keto sugar, an eco-friendly radical cleavage of a bromomethyl group, and an efficient preparation of a fluorodisaccharide via the use of XtalFluor-E.
