136838-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136838-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,3 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 136838-40:
(8*1)+(7*3)+(6*6)+(5*8)+(4*3)+(3*8)+(2*4)+(1*0)=149
149 % 10 = 9
So 136838-40-9 is a valid CAS Registry Number.

Efficient Free-Radical and Palladium-Catalyzed Tandem Alkene Insertions: A New Approach to Benzoprostacyclins
Larock, Richard C.,Lee, Nam Ho
, p. 6253 - 6254 (2007/10/02)
Several stereoisomeric benzoprostacyclins are readily available from a common intermediate (11) via free-radical and palladium-promoted tandem alkene insertion processes.
