115887-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115887-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,8,8 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 115887-80:
(8*1)+(7*1)+(6*5)+(5*8)+(4*8)+(3*7)+(2*8)+(1*0)=154
154 % 10 = 4
So 115887-80-4 is a valid CAS Registry Number.

An enantiospecific route to C,D ring synthons for steroid synthesis
Clase, J. Andrew,Money, Thomas
, p. 1537 - 1544 (2007/10/02)
A simple enantiospecific route to a hydrindenone intermediate for steroid synthesis has been accomplished.The introduction of a wide variety of side-chain units is made possible by stereoselective alkylation of a bicyclic ester 13 derived from (+)-camphor
