Check Digit Verification of cas no

The CAS Registry Mumber 150849-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,8,4 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 150849-75:
(8*1)+(7*5)+(6*0)+(5*8)+(4*4)+(3*9)+(2*7)+(1*5)=145
145 % 10 = 5
So 150849-75-5 is a valid CAS Registry Number.

, 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

Iodine monobromide (IBr) at low temperature: A superior protocol for diastereoselective cyclizations of homoallylic carbonates

Duan, James J. -W.,Sprengeler, Paul A.,Smith III, Amos B.

, p. 6439 - 6442 (2007/10/02)

Iodine monobromide (IBr) induces efficient electrophilic cyclizations of homoallylic t-butyl carbonates in toluene or methylene chloride at low temperature, affording significantly better diastereoselectivity than iodine (I2) in acetonitrile.
