Check Digit Verification of cas no
The CAS Registry Mumber 21020-26-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,2 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21020-26:
(7*2)+(6*1)+(5*0)+(4*2)+(3*0)+(2*2)+(1*6)=38
38 % 10 = 8
So 21020-26-8 is a valid CAS Registry Number.

REACTIONS OF 3-ALKYL- AND 3,3-DIALKYL-1-BROMOALLENES WITH ORGANOCUPRATES: EFFECTS OF THE NATURE OF THE CUPRATE REAGENT ON THE REGIO- AND STEREOSELECTIVITY
Caporusso, Anna Maria,Polizzi, Carmela,Lardicci, Luciano
, p. 6073 - 6076 (2007/10/02)
Organocuprates induce 1,3- and direct substitution in 3-alkyl- and 3,3-dialkyl-1-bromo-1,2-dienes leading respectively to either terminal acetylenes or allenic hydrocarbons.The nature of the cuprate exerts a prominent role in determining both the regio- and the stereochemistry of these reactions.
