Check Digit Verification of cas no

The CAS Registry Mumber 133344-32-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,4 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133344-32:
(8*1)+(7*3)+(6*3)+(5*3)+(4*4)+(3*4)+(2*3)+(1*2)=98
98 % 10 = 8
So 133344-32-8 is a valid CAS Registry Number.

HALOENAMINES - II. A RAPID AND EFFICIENT SYNTHESIS OF CARBOHYDRATE 1,2-ORTHOESTERS

Ernst, Beat,Mesmaeker, Alain De,Wagner, Beatrice,Winkler, Tammo

, p. 6167 - 6170 (1990)

Carbohydrate exo 1,2-orthoesters are obtained in good to excellent yields by treating furanose and pyranose hemiacetals first with 1.1 eq. 1-chloro-2,N,N-trimethyl-propenylamine and then with the appropriate alcohols in the presence of NEt3.
