Check Digit Verification of cas no

The CAS Registry Mumber 521973-41-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,1,9,7 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 521973-41:
(8*5)+(7*2)+(6*1)+(5*9)+(4*7)+(3*3)+(2*4)+(1*1)=151
151 % 10 = 1
So 521973-41-1 is a valid CAS Registry Number.

1,3-Dipolar cycloaddition of ethyl propiolate to 4,4-dimethyl- 4,5-dihydro-1,2-dithiolo-[5,4-c]quinoline-1-thiones

Medvedeva,Shikhaliev,Ermolova,Solov'Ev,Shatalov

, p. 918 - 921 (2002)

The interaction of ethyl propiolate with 4,4-dimethyl-4,5-dihydro-2,3-dithiolo[3,4-c]quinoline-1-thiones leads to 1,3-dithiol-2-ylidenes, 1,6,6a(λ4)-trithiapentalene, or thiino[2,3-c]quinolines depending on the conditions.
