138736-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138736-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,3 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138736-89:
(8*1)+(7*3)+(6*8)+(5*7)+(4*3)+(3*6)+(2*8)+(1*9)=167
167 % 10 = 7
So 138736-89-7 is a valid CAS Registry Number.

Stereoselective synthesis of a steroidal trans-hydrindanone synthon from (R)-limonene
Kim,Lee
, p. 6885 - 6886 (2007/10/02)
The trans-hydrindanone 1 was synthesized from (R)-limonene (2) in a highly stereoselective manner by an intramolecular ester enolate alkylation and metal-halogen exchange-initiated anionic cyclization.
