Check Digit Verification of cas no

The CAS Registry Mumber 70489-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,4,8 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 70489-49:
(7*7)+(6*0)+(5*4)+(4*8)+(3*9)+(2*4)+(1*9)=145
145 % 10 = 5
So 70489-49-5 is a valid CAS Registry Number.

A total synthesis and structural aspects of racemic 8-oxygenated tetracyclines

Glatz,Helmchen,Muxfeldt,et al.

, p. 2171 - 2181 (1979)

A stereoselective total synthesis of the first 8-oxygenated tetracycline derivatives 43 and 4 is described. Key steps for the construction of the tetracycline skeleton are the condensation of the tetralone aldehyde 24 with the thiazolone 32 followed by co
