1222559-13-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1222559-13-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,2,5,5 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1222559-13:
(9*1)+(8*2)+(7*2)+(6*2)+(5*5)+(4*5)+(3*9)+(2*1)+(1*3)=128
128 % 10 = 8
So 1222559-13-8 is a valid CAS Registry Number.

A novel access to dispirocyclohexanoneindano pyrrolidines
Poornachandran, Mahalingam,Raghunathan, Raghavachary
experimental part, p. 127 - 130 (2010/04/29)
Synthesis of a series of novel dispirocyclohexanoneindano pyrrolidines has been described. The cycloaddition reaction of azomethine ylide generated from ninhydrin and sarcosine with bisarylidenecyclohexanones was found to be highly regionselective.
