Check Digit Verification of cas no

The CAS Registry Mumber 67649-77-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,4 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 67649-77:
(7*6)+(6*7)+(5*6)+(4*4)+(3*9)+(2*7)+(1*7)=178
178 % 10 = 8
So 67649-77-8 is a valid CAS Registry Number.

Stereoselective synthesis of 1,1-bimetalloalkenes of tin and selenium, tin and tellurium

Park, Chan Pil,Sung, Jin Wuk,Oh, Dong Young

, p. 1055 - 1056 (1999)

1,1-Bimetalloalkenes(tin and selenium, tin and tellurium) were stereoselectively prepared by a hydrozirconation of acetylenic stannanes followed by transmetallation using tellurenyl iodide and selenenyl bromide. One equivalent of n-BuLi displaced a trialk

Kabalka, George W.,Venkataiah, Bollu

, p. 3703 - 3705 (2007/10/03)

Vinylboronic acids and vinylboronic esters react with phenylselenyl chloride in ionic liquids to generate vinyl selenides stereospecifically.

Vicinal di£unctionalization of alkynyl selenides with lithium butylcyano cuprate and electrophiles

Braga,Reckziegel,Silveira,Comasseto

, p. 1165 - 1170 (2007/10/02)

Alkynyl selenides react with lithium butylcyano cuprate giving an intermediate lithium vinylcyano cuprate, which is trapped with electrophiles to give several classes of vinylic selenides.
