Check Digit Verification of cas no

The CAS Registry Mumber 60631-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,6,3 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 60631-76:
(7*6)+(6*0)+(5*6)+(4*3)+(3*1)+(2*7)+(1*6)=107
107 % 10 = 7
So 60631-76-7 is a valid CAS Registry Number.

Asymmetric diels-alder reactions of α,β-unsaturated aldehydes catalyzed by a diarylprolinol silyl ether salt in the presence of water

Hayashi, Yujiro,Samanta, Sampak,Gotoh, Hiroaki,Ishikawa, Hayato

supporting information; experimental part, p. 6634 - 6637 (2009/03/12)

(Chemical Equation Presented) Water, water, everywhere: The title reaction predominantly affords the exo isomer with excellent enantioselectivity (see scheme; TMS=trimethylsilyl). The synthesis can be carried out without organic solvents and provides the products by distillation. Water increases the rate and enantioselectivity of the reaction.
