126971-22-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126971-22-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,9,7 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 126971-22:
(8*1)+(7*2)+(6*6)+(5*9)+(4*7)+(3*1)+(2*2)+(1*2)=140
140 % 10 = 0
So 126971-22-0 is a valid CAS Registry Number.

, p. 814 - 817 (2007/10/02)
Efficient syntheses of enantiomerically pure cyclopentadienes which undergo stereoselective and regioselective high pressure cycloadditions with nonsymmetric dienophiles are reported.As these compounds show a quite high chemical as well as thermal stabili
