Check Digit Verification of cas no

The CAS Registry Mumber 140868-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,6 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140868-90:
(8*1)+(7*4)+(6*0)+(5*8)+(4*6)+(3*8)+(2*9)+(1*0)=142
142 % 10 = 2
So 140868-90-2 is a valid CAS Registry Number.

Stereoselective synthesis of 2-functionalized 1-bromo-1-iodo-1-alkenes by electrophilic iodination of 1-bromo-1-alkynes

Barluenga,Rodriguez,Campos

, p. 270 - 272 (1992)

1-Bromo-1-alkynes 1 react with bis(pyridine)iodine(1) tetrafluoroborate (2) and nucleophiles (AcOH, HCO2H, Cl-, Br-, I-) to give in a stereoselective addition 2-functionalized 1-bromo-1-iodo-1-alkenes 3.
