Check Digit Verification of cas no

The CAS Registry Mumber 499105-51-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,9,1,0 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 499105-51:
(8*4)+(7*9)+(6*9)+(5*1)+(4*0)+(3*5)+(2*5)+(1*1)=180
180 % 10 = 0
So 499105-51-0 is a valid CAS Registry Number.

Carbon-nitrogen bond formation between allyl silyl ether and hydrazide promoted by mercuric triflate catalyst

, p. 1069 - 1073 (2012/06/04)

An efficient method for carbon-nitrogen bond formation between ally silyl ethers and N,N-acyltosylhydrazine was developed under very mild conditions using 2 mol% of mercuric triflate [Hg(OTf) as a catalyst. This method does not require the use of any ligand system or supplementary additives and is applicable to the preparation of various N-allylhydrazides with good to excellent yields.
