Check Digit Verification of cas no

The CAS Registry Mumber 126441-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,4,4 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 126441-74:
(8*1)+(7*2)+(6*6)+(5*4)+(4*4)+(3*1)+(2*7)+(1*4)=115
115 % 10 = 5
So 126441-74-5 is a valid CAS Registry Number.

Technetium-99m-labeling and synthesis of thymidine analogs: Potential candidates for tumor imaging

Teng, Bao,Bai, Yunpeng,Chang, Yu,Chen, Shizhen,Li, Zhaolong

, p. 3440 - 3444 (2008/02/10)

The technetium-99m-labeling and synthesis of a series of thymidine analogs were studied. The target molecules were obtained by using 6-hydrazinopyridine-3-carboxylic acid (HYNIC) as a bifunctional coupling agent and using N-(2-hydroxy-1,1-bis(hydroxymethyl)ethyl)glycine (tricine) and ethylenediamine-N,N′-diacetic acid (EDDA) as coligands. The effects of different spacers between thymidine analog with HYNIC on radiochemical yield were also studied.
