Check Digit Verification of cas no
The CAS Registry Mumber 190384-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,3,8 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 190384-95:
(8*1)+(7*9)+(6*0)+(5*3)+(4*8)+(3*4)+(2*9)+(1*5)=153
153 % 10 = 3
So 190384-95-3 is a valid CAS Registry Number.

On the reaction of chloroalkylbenzothiazoles with alkaloides
Florio, Saverio,Capriati, Vito,Colli, Gennara
, p. 5839 - 5846 (2007/10/03)
2-chloroalkylbenzothiazoles 1a-c react with alkoxides to give substitution and ring-expanded products 3 and 4. The substitution ring-enlargement competition much depends upon the solvent, the substitution reaction being preferred in alcohols and the ring-enlargement in DMF.
