Check Digit Verification of cas no

The CAS Registry Mumber 1220042-37-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,0,4 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1220042-37:
(9*1)+(8*2)+(7*2)+(6*0)+(5*0)+(4*4)+(3*2)+(2*3)+(1*7)=74
74 % 10 = 4
So 1220042-37-4 is a valid CAS Registry Number.

Ag-containing all-carbon 1,3-dipoles: Generation and formal cycloaddition for furo[3,2-b]-β/γ-lactams

Zhang, Zhiguo,Zhang, Qian,Ni, Zhikun,Liu, Qun

supporting information; experimental part, p. 1269 - 1271 (2010/07/05)

A new strategy for highly diastereoselective synthesis of furo[3,2-b]-β-lactams and furo[3,2-b]-γ-lactams via a novel Ag(i)-mediated intramolecular 1,3-dipolar cycloaddition of oxo-N- propargylamides, is developed and the possible mechanism of these trans
