Check Digit Verification of cas no

The CAS Registry Mumber 1311109-81-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,1,1,0 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1311109-81:
(9*1)+(8*3)+(7*1)+(6*1)+(5*1)+(4*0)+(3*9)+(2*8)+(1*1)=95
95 % 10 = 5
So 1311109-81-5 is a valid CAS Registry Number.

An efficient approach to the synthesis of nucleosides: Gold(I)-catalyzed N-glycosylation of pyrimidines and purines with glycosyl ortho-alkynyl benzoates

Zhang, Qingju,Sun, Jiansong,Zhu, Yugen,Zhang, Fuyi,Yu, Biao

supporting information; experimental part, p. 4933 - 4936 (2011/06/24)

Persuaded with gold: The title reaction in the presence of [Ph 3PAuNTf2] (Tf=trifluoromethanesulfonyl) led conveniently to the corresponding nucleosides with excellent regioselectivity (see scheme). Even purine derivatives underwent this transformation owing to the mild conditions, which enabled the use of protecting groups that would not usually be compatible with N-glycosylation conditions.
