Check Digit Verification of cas no

The CAS Registry Mumber 144262-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,6 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 144262-07:
(8*1)+(7*4)+(6*4)+(5*2)+(4*6)+(3*2)+(2*0)+(1*7)=107
107 % 10 = 7
So 144262-07-7 is a valid CAS Registry Number.

STUDIES ON THE SYNTHESIS OF C-2 SUBSTITUTED CEPHALOSPORIN SULFONES: THE UNEXPECTED REACTIVITY OF THE C-2 CARBON

Botta, Maurizio,Crucianelli, Marcello,Saladino, Raffaele,Nicoletti, Rosario

, p. 1375 - 1384 (2007/10/02)

An interesting route for the synthesis of C-2 substituted cephalosporin sulfones (8) has been described along with an unexpected reactivity on the C-2 carbon of C-2 substituted cephalosporin sulfoxides and sulfones.
