Check Digit Verification of cas no
The CAS Registry Mumber 19781-82-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,8 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19781-82:
(7*1)+(6*9)+(5*7)+(4*8)+(3*1)+(2*8)+(1*2)=149
149 % 10 = 9
So 19781-82-9 is a valid CAS Registry Number.

Iodine Monobromide (IBr) at Low Temperature: Enhanced Diastereoselectivity in Electrophilic Cyclizations of Homoallylic Carbonates
Duan, James J.-W.,Smith, Amos B.
, p. 3703 - 3711 (2007/10/02)
Iodine monobromide affords superior diastereoselectivity in low-temperature electrophilic cyclizations of homoallylic carbonates.Solvent and temperature effects and the scope and limitations of the method are discussed; optimal selectivity is obtained in
