Check Digit Verification of cas no

The CAS Registry Mumber 1237507-21-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,7,5,0 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1237507-21:
(9*1)+(8*2)+(7*3)+(6*7)+(5*5)+(4*0)+(3*7)+(2*2)+(1*1)=139
139 % 10 = 9
So 1237507-21-9 is a valid CAS Registry Number.

Catalytic activity studies of aminocarbonyl group containing hoveyda-grubbs-type complexes for the syntheses of herbarumin i and stagonolide A

Mohapatra, Debendra K.,Somaiah,Rao, M. Mallikarjuna,Caijo, Frederic,Mauduit, Marc,Yadav

, p. 1223 - 1226 (2010)

The catalytic activity of four aminocarbonyl group containing boomerang-type ring-closing metathesis catalysts have been studied for ten-membered lactone and compared well with the Grubbs I and II as well as the Hoveyda-Grubbs catalysts. The activity was found to be superior to the above three ring-closing metathesis catalysts and suggesting novel stereoselective total syntheses of herbarumin I and stagonolide A.
