Check Digit Verification of cas no

The CAS Registry Mumber 450406-83-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,0,4,0 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 450406-83:
(8*4)+(7*5)+(6*0)+(5*4)+(4*0)+(3*6)+(2*8)+(1*3)=124
124 % 10 = 4
So 450406-83-4 is a valid CAS Registry Number.

Candida rugosa lipase-catalyzed enantioselective hydrolysis in organic solvents. Convenient preparation of optically pure 2-hydroxy-2-arylethanephosphonates

Zhang, Yonghui,Li, Zuyi,Yuan, Chengye

, p. 3247 - 3249 (2007/10/03)

A convenient enzymatic method is presented for the preparation of optically pure 2-hydroxy-2-arylethanephosphonates. It is proved that 2-butyryloxy-2-arylethanephosphonates can be enantioselectively hydrolyzed in diisopropyl ether equilibrated with water
