Check Digit Verification of cas no
The CAS Registry Mumber 850816-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,8,1 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 850816-24:
(8*8)+(7*5)+(6*0)+(5*8)+(4*1)+(3*6)+(2*2)+(1*4)=169
169 % 10 = 9
So 850816-24-9 is a valid CAS Registry Number.

A stable N-heterocyclic carbene with a diboron backbone
Krahulic, Kelly E.,Enright, Gary D.,Parvez, Masood,Roesler, Roland
, p. 4142 - 4143 (2005)
The synthesis of a novel five-membered inorganic ring, a stable N-heterocyclic carbene with a diboron backbone, is reported. A pentacarbonyltungsten complex containing the new carbene is also described. Spectroscopic evidence indicates that the sterically
