Check Digit Verification of cas no

The CAS Registry Mumber 91109-12-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,0 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91109-12:
(7*9)+(6*1)+(5*1)+(4*0)+(3*9)+(2*1)+(1*2)=105
105 % 10 = 5
So 91109-12-5 is a valid CAS Registry Number.

BENZENESULFONYLCARBONITRILE OXIDE. 5. FACE SELECTIVITY OF CYCLOADDITION TO CHIRAL TERMINAL ALKENES

Wade, Peter A.,Singh, Shankar M.,Pillay, M. Krishna

, p. 601 - 612 (2007/10/02)

The diastereomer ratio for cycloaddition of benzenesulfonylcarbonitrile oxide (BSNO) to a series of (S)-vinylglycine-derived alkenes varied from 30:70 to 66:34 depending on the substituents at the chiral center.Isomer ratios were routinely determined by (

FUROXANS AS NITRILE OXIDE PRECURSORS: CYCLOADDITION REACTIONS OF BIS(BENZENESULFONYL)FUROXAN.

Whitney, Ralph A.,Nicholas, Everton S.

, p. 3371 - 3374 (2007/10/02)

Bis(benzenesulfonyl)furoxan has been shown to undergo cycloaddition reactions with dipolarophiles in refluxing xylene to give benzenesulfonylnitrile oxide cycloadducts.
