Check Digit Verification of cas no

The CAS Registry Mumber 276680-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,6,6,8 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 276680-25:
(8*2)+(7*7)+(6*6)+(5*6)+(4*8)+(3*0)+(2*2)+(1*5)=172
172 % 10 = 2
So 276680-25-2 is a valid CAS Registry Number.

Synthesis of some 5-furfuryl pyrido[2,3-d] pyrimidines and 1-ethyl-5-furfuryl pyrido[2,3-d] pyrimidines as possible antitumor & anticancer agents

Singh, Gajendra,Sharma, Anoop K.,Mishra,Prakash

, p. 83 - 93 (2007/10/03)

Synthesis of some novel 5-furfuryl pyrido[2,3-d]pyrimidines was carried out by the condensation of 2-amino-3-cyano-4-furfuryl-6-substituted pyridine with various arylisothiocyanates, thiourea and carbondisulphide. These compounds on treatment with ethylbromide using phase transfer catalyst gave 1-ethyl-5-furfuryl pyrido[2,3-d]pyrimidines. The structure of the compounds has been established by elemental, IR and NMR studies. The compounds thus synthesized were screened for their antimicrobial activity.
