Check Digit Verification of cas no

The CAS Registry Mumber 31598-95-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,9 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 31598-95:
(7*3)+(6*1)+(5*5)+(4*9)+(3*8)+(2*9)+(1*5)=135
135 % 10 = 5
So 31598-95-5 is a valid CAS Registry Number.

Stereoselective synthesis of (Z)-β-chlorovinyl sulfones by addition of sulfonyl chlorides to acetylenes

Liu, Xueyuan,Duan, Xinhua,Pan, Zhenliang,Han, Yao,Liang, Yongmin

, p. 1752 - 1754 (2005)

The addition reaction of sulfonyl chlorides with acetylenes in the presence of a copper salt is described. The reaction proceeds in toluene in the presence of CuCl with Me2S as the additive to afford only (Z)-β-chlorovinyl sulfones in moderate to excellent yields. Georg Thieme Verlag Stuttgart.
