Check Digit Verification of cas no

The CAS Registry Mumber 23903-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,0 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23903-82:
(7*2)+(6*3)+(5*9)+(4*0)+(3*3)+(2*8)+(1*2)=104
104 % 10 = 4
So 23903-82-4 is a valid CAS Registry Number.

Catalytic asymmetric synthesis of cyclopropylphosphonates - Catalysts' scope and reactivity

Charette, Andre B.,Bouchard, Jean-Emmanuel

, p. 533 - 542 (2005)

The transition metal-catalyzed cyclopropanation of alkenes using α-diazomethylphosphonates leads to cyclopropylphosphonate derivatives in high yields. The reaction proceeds well with copper, rhodium, and ruthenium catalysts. The best catalysts for the ena
