Check Digit Verification of cas no

The CAS Registry Mumber 1377955-01-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,7,9,5 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1377955-01:
(9*1)+(8*3)+(7*7)+(6*7)+(5*9)+(4*5)+(3*5)+(2*0)+(1*1)=205
205 % 10 = 5
So 1377955-01-5 is a valid CAS Registry Number.

A facile and efficient ultrasound-assisted stereospecific synthesis of novel bicyclo-cyclopropanes

Ben Hamadi, Naoufel,Msaddek, Moncef

, p. 409 - 413 (2012)

The regispecific synthesis of pyrazolines has been accomplished through the 1,3-dipolar cycloaddition of 2-diazopropane to pyridazine-3,6-dione derivatives. A convenient and inexpensive ultrasound-assisted preparation of bicyclo-cyclopropanes in a completely stereoselective manner in almost quantitative yields has been realized. The highly stereoselective extrusion of nitrogen suggests a concerted mechanism.
