Check Digit Verification of cas no

The CAS Registry Mumber 70769-82-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,7,6 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 70769-82:
(7*7)+(6*0)+(5*7)+(4*6)+(3*9)+(2*8)+(1*2)=153
153 % 10 = 3
So 70769-82-3 is a valid CAS Registry Number.

Preparation of thiochromans via thermal cyclization

Jensen,Manczuk,Nelson,Caswell,Fleming

, p. 1527 - 1531 (2007/10/03)

Formation of the thiochroman ring system is achieved by a two step synthesis that involves heating 3-thiophenyl-1-propanols or 4-thiophenyl-2-butanols in toluene with catalytic amounts of p-toluenesulfonic acid. The propanols are made by the addition of s
