Check Digit Verification of cas no

The CAS Registry Mumber 358975-42-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,8,9,7 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 358975-42:
(8*3)+(7*5)+(6*8)+(5*9)+(4*7)+(3*5)+(2*4)+(1*2)=205
205 % 10 = 5
So 358975-42-5 is a valid CAS Registry Number.

2-Arylethenyl-2′-arylethynyl sulfones: A potential source for some spiroheterocycles

Bhaskar Reddy,Chandrasekhar Babu,Padmavathi

, p. 769 - 772 (2007/10/03)

The double Michael addition of dimethyl malonate to 2-arylethenyl-2′-arylethynyl sulfones (3) resulted in 3,5-diaryl-5,6-dihydro-4,4-dimethoxycarbonyl-1-thiin-1,1-dioxides (4). The latter on cyclocondensation with urea / thiourea / hydrazine hydrate / hydroxylamine hydrochloride gave spiroheterocycles.
