Check Digit Verification of cas no

The CAS Registry Mumber 91075-76-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,7 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91075-76:
(7*9)+(6*1)+(5*0)+(4*7)+(3*5)+(2*7)+(1*6)=132
132 % 10 = 2
So 91075-76-2 is a valid CAS Registry Number.

REACTIVITY OF ARYLAZOMETHYLENETRIPHENYLPHOSPHORANES TOWARDS ELECTROPHILES: REACTION WITH CS2

Alemagna, A.,Buttero, P. del,Licandro, E.,Maiorana, S.,Trave, R.

, p. 935 - 976 (2007/10/02)

The title reaction proceeds via the direct attack of the electrophilic reagent onto the nitrogen atom β to the ylidic carbon of the phosphoranes, followed by ring closure to 4-aryl-1,3,4-thiadiazoline-5-thiones, with elimination of PPh3.
