Check Digit Verification of cas no

The CAS Registry Mumber 337510-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,7,5,1 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 337510-87:
(8*3)+(7*3)+(6*7)+(5*5)+(4*1)+(3*0)+(2*8)+(1*7)=139
139 % 10 = 9
So 337510-87-9 is a valid CAS Registry Number.

Ring-selective synthesis of O-heterocycles from acyclic 3-O-allyl-monosaccharides via intramolecular nitrone-alkene cycloaddition

Shing, Tony K.M,Zhong, Yong-Li

, p. 1573 - 1579 (2001)

Intramolecular 1,3-dipolar cycloadditions of nitrones formed from 3-O-allyl-D-glucose and D-altrose (both with threo-configuration at C-2,3) afford oxepanes selectively whereas the same reactions of nitrones derived from 3-O-allyl-D-allose and D-mannose (both with erythro-configuration at C-2,3) give tetrahydropyrans selectively.
