Check Digit Verification of cas no

The CAS Registry Mumber 1312025-58-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,0,2 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1312025-58:
(9*1)+(8*3)+(7*1)+(6*2)+(5*0)+(4*2)+(3*5)+(2*5)+(1*8)=93
93 % 10 = 3
So 1312025-58-3 is a valid CAS Registry Number.

A one-pot procedure for methylenating carbonyl compounds using the Nysted reagent and titanocene dichloride

Haahr, Adam,Rankovic, Zoran,Hartley, Richard C.

, p. 3020 - 3022 (2011)

The combination of the Nysted reagent and titanocene dichloride methylenates aldehydes and ketones to give alkenes, and in a microwave-assisted process, esters and lactones give enol ethers. The methylenating agent in this one-pot procedure is presumed to be titanocene methylidene, which is the same reactive intermediate as that generated from Tebbe, Petasis and Grubbs reagents, each of which have to be prepared before use.
