Check Digit Verification of cas no

The CAS Registry Mumber 1403611-75-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,6,1 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1403611-75:
(9*1)+(8*4)+(7*0)+(6*3)+(5*6)+(4*1)+(3*1)+(2*7)+(1*5)=115
115 % 10 = 5
So 1403611-75-5 is a valid CAS Registry Number.

CuI controlled C-C and C-N bond formation of heteroaromatics through C(sp3)-H activation

Xia, Ran,Niu, Hong-Ying,Qu, Gui-Rong,Guo, Hai-Ming

supporting information, p. 5546 - 5549 (2013/01/15)

A new method for C-C and C-N bond formation of heteroaromatics and C(sp3)-H alkanes was developed with high regioselectivity. The reaction occurred on C8 to give 8-cylcoakylpurines by C-C bond formation only promoted by tBuOOtBu, while it occurred on the amino group to give N6-alkylated purines by C-N bond formation when 2 equiv of CuI were added. A reaction mechanism was also proposed based on our preliminary experimental data.
