Check Digit Verification of cas no
The CAS Registry Mumber 6229-00-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,2 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6229-00:
(6*6)+(5*2)+(4*2)+(3*9)+(2*0)+(1*0)=81
81 % 10 = 1
So 6229-00-1 is a valid CAS Registry Number.

Silicon-carbon unsaturated compounds. 62. Reactions of silenes produced thermally from pivaloyl- and adamantoyltris(trimethylsilyl)silane with mono(silyl)acetylenes
Naka, Akinobu,Ishikawa, Mitsuo
, p. 248 - 255 (2000)
Thermolysis of pivaloyltris(trimethylsilyl)silane (1a) with tert-butyldimethylsilylacetylene at 120°C gave 2-tert-butyl-3-tert-butyldimethylsilyl-2-trimethylsiloxy-1,1-bis(trimethylsilyl) -1-silacyclobut-3-ene (2a). Similar treatment of adamantoyltris(trimethylsilyl)silane (1b) at 120°C produced 2-adamantyl-3-tert-butyldimethylsilyl-2-trimethylsiloxy-1,1-bis(trimethylsilyl)- 1-silacyclobut-3-ene (2b). Thermolysis of 1a with tert-butyldimethylsilylacetylene at 160°C, however, gave 1-tert-butyl-1-(tert-butyldimethylsilyl)-3-[(trimethylsiloxy)bis(trimethylsilyl) silyl]-1,2-propadiene (3a), along with 1:2 adduct (4a). Similar reaction of 1b gave 1-adamantyl-1-(tert-butyldimethylsilyl)-3-[(trimethylsiloxy)bis(trimethylsilyl) silyl]-1,2-propadiene (3b) similar to 3a, together with 1:2 adduct (4b). Thermolysis of 1a and 1b in the presence of dimethylphenylsilylacetylene or triphenylsilylacetylene at 120°C produced [2 + 2] cycloadducts arising from the reaction of silenes generated thermally from 1a and 1b with mono(silyl)acetylenes analogous 2a and 2b, along with small amounts of 1:2 adducts. At 160°C, the similar treatment of 1a and 1b afforded propadiene derivatives arising from the ring opening reactions of [2 + 2] cycloadducts, in addition to 1:2 adducts.
