Check Digit Verification of cas no
The CAS Registry Mumber 76685-89-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,6,8 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 76685-89:
(7*7)+(6*6)+(5*6)+(4*8)+(3*5)+(2*8)+(1*9)=187
187 % 10 = 7
So 76685-89-7 is a valid CAS Registry Number.

BORON ANNULATION: TOTAL SYNTHESIS OF (+/-)-ESTRONE METHYL ETHER
Bryson, Thomas A.,Reichel, Curtis J.
, p. 2381 - 2384 (2007/10/02)
The stereoselective hydroboration and carbonylation of highly functionalized 1,4-dienes affords trans-hydrindanones in good yield.These trans-hydrindanones are synthons for norpregnenolone, estrone and related estradiol derivatives.
