1250244-71-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1250244-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,0,2,4 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1250244-71:
(9*1)+(8*2)+(7*5)+(6*0)+(5*2)+(4*4)+(3*4)+(2*7)+(1*1)=113
113 % 10 = 3
So 1250244-71-3 is a valid CAS Registry Number.

Palladium-catalyzed reaction of 4-cyclopentene-1,3-diol monoacetate with Grignard reagents producing hitherto unreachable cis-1,2-isomers
Hattori, Hatsuhiko,Abbas, Ashraf A.,Kobayashi, Yuichi
, p. 884 - 885 (2004)
Reaction of 4-cyclopentene-1,3-diol monoacetate with RMgCl (R = alkyl, aryl) in the presence of a palladium catalyst proceeded with retention of configuration to give cis-1,2-regio-isomers as the major products.
