Check Digit Verification of cas no

The CAS Registry Mumber 1260388-49-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,3,8 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1260388-49:
(9*1)+(8*2)+(7*6)+(6*0)+(5*3)+(4*8)+(3*8)+(2*4)+(1*9)=155
155 % 10 = 5
So 1260388-49-5 is a valid CAS Registry Number.

A highly efficient synthesis of sulphonamide derivatives in the presence of n-methyl-2-pyrrolidone

Tan, Yong,Wang, Su Juan,Wang, Yi Ting,Gao, Bao Xiang,Ba, Xin Wu

experimental part, p. 3648 - 3653 (2010/12/25)

The sulphonamide derivatives are synthesized by two component condensation of alkyl bromide and sodium arylsulphonamide using N-methyl-2-pyrrolidone (NMP) as a reaction medium. This method results in high yields without the formation of unwanted side products, and expanding substrate scopes. Copyright
