Check Digit Verification of cas no

The CAS Registry Mumber 77971-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,7 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77971-20:
(7*7)+(6*7)+(5*9)+(4*7)+(3*1)+(2*2)+(1*0)=171
171 % 10 = 1
So 77971-20-1 is a valid CAS Registry Number.

DIE CHEMIE DER SCHWEREN CARBEN-ANALOGEN R2M, M = Si, Ge, Sn IX. EIGENSCHAFTEN UND THERMOLYSE VON NEUEN 7-SILABICYCLOHEPTADIENEN

Appler, Hubertus,Gross, Lutz W.,Mayer, Bernd,Neumann, Wilhelm P.

, p. 9 - 24 (2007/10/02)

Factors governing the ease and mechanism of 7-silabicycloheptadienes thermolysis in order to generate free silylenes and the corresponding benzene derivatives are investigated.For this purpose, 29 new compounds of the types VII-X have been prepared

OBSERVATIONS AND COMMENTS ON THE THERMAL BEHAVIOR OF 7-SILANORBORNADIENES

Barton, Thomas J.,Goure, William F.,Witiak, Joanne L.,Wulff, William D.

, p. 87 - 106 (2007/10/02)

Evidence for a radical mechanism in the termal decomposition of a 7-silanorbornadiene is presented.It is demonstrated that 2-carboxy-7-silanorbornadienes undergo a formal 1,5-migration of silicon to form O-silyl enol ethers.An earlier suggested rearrangement of a 7-silanorbornadiene to a silepin or silanorcardiene is excluded.A recent report of thermal and photochemical epimerization of 7-silanorbornadienes is shown to be incorrect.
