Check Digit Verification of cas no

The CAS Registry Mumber 1260676-83-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,6,7 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1260676-83:
(9*1)+(8*2)+(7*6)+(6*0)+(5*6)+(4*7)+(3*6)+(2*8)+(1*3)=162
162 % 10 = 2
So 1260676-83-2 is a valid CAS Registry Number.

Efficient solution-phase synthesis of 4,5,7-trisubstituted pyrrolo[3,2- d ]pyrimidines

Zhang, Weihe,Liu, Jing,Stashko, Michael A.,Wang, Xiaodong

supporting information, p. 10 - 19 (2013/02/26)

We have developed an efficient and robust route to synthesize 4,5,7-trisubstituted pyrrolo[3,2-d]pyrimidines as potent kinase inhibitors. This solution-phase synthesis features a SNAr substitution reaction, cross-coupling reaction, one-pot reduction/reductive amination and N-alkylation reaction. These reactions occur rapidly with high yields and have broad substrate scopes. A variety of groups can be selectively introduced into the N5 and C7 positions of 4,5,7-trisubstituted pyrrolopyrimidines at a late stage of the synthesis, thereby providing a highly efficient approach to explore the structure-activity relationships of pyrrolopyrimidine derivatives. Four synthetic analogs have been profiled against a panel of 48 kinases and a new and selective FLT3 inhibitor 9 is identified.
