69822-73-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69822-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,2 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 69822-73:
(7*6)+(6*9)+(5*8)+(4*2)+(3*2)+(2*7)+(1*3)=167
167 % 10 = 7
So 69822-73-7 is a valid CAS Registry Number.

A preparation of high specific activity [11,12-3H]-9-cis-retinoic acid
Coe,Hawes,Towers
, p. 587 - 594 (2007/10/02)
A selective total synthesis of [11,12-3H]-9-cis-retinoic acid 1 at a specific activity of 46 Ci/mmole is described. The alkyne 4, efficiently prepared in two steps from readily available starting materials, was partially reduced to 9,11-di-cis-
