Check Digit Verification of cas no

The CAS Registry Mumber 85157-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,1,5 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 85157-50:
(7*8)+(6*5)+(5*1)+(4*5)+(3*7)+(2*5)+(1*0)=142
142 % 10 = 2
So 85157-50-2 is a valid CAS Registry Number.

A Novel Cyclization of 1,2-Bis(2,2-dibromocyclopropyl)benzenes with Methyllithium

Hoehn, Juergen,Weyerstahl, Peter

, p. 808 - 814 (2007/10/02)

The CBr2 bis adducts 7, 8, and 10 react with MeLi at - 78 deg C to give the dicyclopropanaphthalenes 17 - 19.Thus, from meso-7 syn-17, and from d,l-7 anti-17 are formed stereoselectively.The reaction may proceed via the intermediates A or B.The carbenoid
