157121-95-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 157121-95-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,2 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 157121-95:
(8*1)+(7*5)+(6*7)+(5*1)+(4*2)+(3*1)+(2*9)+(1*5)=124
124 % 10 = 4
So 157121-95-4 is a valid CAS Registry Number.

Asymmetric syntheses of isostegane derivatives using trivalent iodine reagents

Pelter, Andrew,Ward, Robert S.,Abd-el-Ghani, Atef

, p. 1353 - 1357 (1996)

Two asymmetric syntheses of the isostegane derivative (+)-3 are reported, both involving oxidation of a homochiral 2,3-dibenzylbutyrolactone with phenyliodonium bis(trifluoroacetate). Of particular interest is the fact that the oxidative step can be carri
