Check Digit Verification of cas no

The CAS Registry Mumber 40232-99-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,3 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40232-99:
(7*4)+(6*0)+(5*2)+(4*3)+(3*2)+(2*9)+(1*9)=83
83 % 10 = 3
So 40232-99-3 is a valid CAS Registry Number.

γ-Radiolysis of 1-Substituted 5-Fluorouracil Derivatives

Kuroda, Tokuyuki,Hisamura, Koji,Matsukuma, Ikuo,Nishikawa, Hiroshi,Nakamizo, Nobuhiro

, p. 674 - 681 (2007/10/02)

A new concept, "Radiation-Induced Drug (RID)", was proposed as a novel type of drugs for cancer therapy.To test the usefulness of this concept, 5-fluorouracil (5-FU) derivatives having various types of substituents at the 1-position were prepared and the γ-radiolyses of their aqueous solutions were studied.The compounds having sulfonyl and thioureido groups as the substituents produced efficiently 5-FU with high G valus upon γ-irradiation.The medium effects on the radiolyses revealed that the above two substituents were removed mainly with HO. and hydrated electrons e-eq.
