Check Digit Verification of cas no

The CAS Registry Mumber 1208170-04-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,8,1,7 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1208170-04:
(9*1)+(8*2)+(7*0)+(6*8)+(5*1)+(4*7)+(3*0)+(2*0)+(1*4)=110
110 % 10 = 0
So 1208170-04-0 is a valid CAS Registry Number.

An efficient and practical synthesis of 2,4-substituted pyrido[4,3-d]pyrimidin-5(6H)-ones

Tian, Xinrong,Suarez, Dominic P.,Li, William Hoi Hong,McSherry, Allison K.,Sanchez, Robert M.,Moore, Michael L.,Axten, Jeffrey M.

supporting information, (2019/11/13)

We describe an efficient synthesis of 2,4-substituted pyrido[4,3-d]pyrimidin-5(6H)-ones, which involves the acid-promoted cyclization of cyano enamine 15 to afford 2,4-bis(methylthio)pyrido[4,3-d]pyrimidin-5(6H)-one 17 as a key intermediate. Selective displacement of the 4-methylthio group by a wide range of anilines followed by oxidation of the 2-methylthio group and subsequent substitution by amines enabled the synthesis of a variety of 2,4-disubstituted pyrido[4,3-d]pyrimidin-5(6H)-ones.
