Check Digit Verification of cas no

The CAS Registry Mumber 89701-79-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,0 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89701-79:
(7*8)+(6*9)+(5*7)+(4*0)+(3*1)+(2*7)+(1*9)=171
171 % 10 = 1
So 89701-79-1 is a valid CAS Registry Number.

REACTIONS OF KETENE ACETALS 16. THE REGIOSPECIFIC SYNTHESIS OF PARTIALLY METHYLATED PURPURINS

Simoneau, Bruno,Brassard, Paul

, p. 3767 - 3774 (2007/10/02)

Two novel vinylketene acetals, 1,4-dimethoxy-1,3-bistrimethylsiloxybutadiene and 1,3,4-trimethoxy-1-trimethylsiloxybutadiene have been prepared in view of their eventual application to the synthesis of the antitumor antibiotic bikaverin.Use of the former in the elaboration of anthraquinones has shown that structures proposed for two natural products, purpurin 1-methyl ether and 8-hydroxypurpurin 1-methyl ether are in fact those of anthragallol derivatives.The second diene has afforded confirmation of the nature of xanthorin 5-methyl ether as well as of a degradation product of bostrycin.A substitution pattern claimed for another natural product, 5-hydroxyanthragallol 2,5-dimethyl ether, is also incorrect.
