Check Digit Verification of cas no

The CAS Registry Mumber 1378521-79-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,8,5,2 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1378521-79:
(9*1)+(8*3)+(7*7)+(6*8)+(5*5)+(4*2)+(3*1)+(2*7)+(1*9)=189
189 % 10 = 9
So 1378521-79-9 is a valid CAS Registry Number.

Nickel-mediated inter- and intramolecular reductive cross-coupling of unactivated alkyl bromides and aryl iodides at room temperature

Yan, Chang-Song,Peng, Yu,Xu, Xiao-Bo,Wang, Ya-Wen

supporting information; experimental part, p. 6039 - 6048 (2012/06/18)

A nickel-mediated intermolecular reductive cross-coupling reaction of unactivated alkyl bromides and aryl iodides at room temperature has been developed and successfully extended to less explored intramolecular versions and tandem cyclization-intermolecular cross-coupling. Highly stereoselective (or stereospecific) synthesis of linear-fused perhydrofuro[2,3-b]furan (pyran) and spiroketal skeletons allows rapid access to these useful building blocks, which would be potentially valuable in the synthesis of relevant natural products. A rational explanation for the formation of contiguous stereogenic centers is given. Copyright
