Check Digit Verification of cas no
The CAS Registry Mumber 27503-78-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,5,0 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 27503-78:
(7*2)+(6*7)+(5*5)+(4*0)+(3*3)+(2*7)+(1*8)=112
112 % 10 = 2
So 27503-78-2 is a valid CAS Registry Number.

, p. 1084 - 1089 (2007/10/02)
A novel method has been developed for the synthesis of sulfonic acids of five-membered heterocycles containing two heteroatoms, with a solution of sulfur trioxide in 1,2-dichloroethane.High yields of the required products are obtained, under conditions which are mild in comparison with those used in earlier methods.The mechanism of sulfonation is discussed, and some azole.SO3 complexes have been obtained and described.
