Check Digit Verification of cas no

The CAS Registry Mumber 1404376-40-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,4,3,7 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1404376-40:
(9*1)+(8*4)+(7*0)+(6*4)+(5*3)+(4*7)+(3*6)+(2*4)+(1*0)=134
134 % 10 = 4
So 1404376-40-4 is a valid CAS Registry Number.

Intramolecular Schmidt reaction of acyl chlorides with alkyl azides: Rapid access to fused polycyclic nitrogen-containing heterocycles via a multistep one-pot transformation

supporting information, p. 5796 - 5799 (2013/01/15)

The first intramolecular Schmidt reaction of acyl chlorides with alkyl azides has been developed. In this one-pot conversion, an ω-azido hydrocinnamic acid is converted to a tricyclic lactam. The most important feature of the process is the efficiency in bond formation (one bond broken and three new bonds created) and ring construction (two new rings formed).
