91708-64-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91708-64-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,0 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91708-64:
(7*9)+(6*1)+(5*7)+(4*0)+(3*8)+(2*6)+(1*4)=144
144 % 10 = 4
So 91708-64-4 is a valid CAS Registry Number.

PALLADIUM-CATALYZED CHIRALITY TRANSFER OF 1,3-DIENE MONOEPOXIDES AND ITS APPLICATION TO THE SYNTHESIS OF STEROID SIDE CHAINS

Takahashi, Takashi,Ootake, Atsushi,Tsuji, Jiro

, p. 1921 - 1924 (2007/10/02)

The palladium-catalyzed 1,4-addition of nucleophiles to 15β,16β-epoxy-E-Δ17(20)-isoheptylidene steroid 8 and 15β,16β-epoxy-E-Δ17(20)-ethylidene steroid 13 has been studied as a good method for regio- and stereoselective introduction of steroid side chains.
