Check Digit Verification of cas no

The CAS Registry Mumber 117755-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,7,5 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 117755-73:
(8*1)+(7*1)+(6*7)+(5*7)+(4*5)+(3*5)+(2*7)+(1*3)=144
144 % 10 = 4
So 117755-73-4 is a valid CAS Registry Number.

Syntheses and Biological Activities of 13-Substituted Avermectin Aglycons

Mrozik, Helmut,Linn, Bruce O.,Eskola, Philip,Lusi, Aino,Matzuk, Alexander,et al.

, p. 375 - 381 (1989)

The reactions of sulfonate esters of the allylic/homoallylic 13-alcohol of 5-O-(tert-butyldimethylsilyl)-22,23-dihydroavermectin B1a aglycon (1a) were investigated.Nucleophilic substitution gave 13β-chloro (2) and 13β-iodo derivatives (4), whil
