Check Digit Verification of cas no

The CAS Registry Mumber 345306-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,5,3,0 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 345306-07:
(8*3)+(7*4)+(6*5)+(5*3)+(4*0)+(3*6)+(2*0)+(1*7)=122
122 % 10 = 2
So 345306-07-2 is a valid CAS Registry Number.

Efficient 1,8- and 1,9-asymmetric inductions in the Grignard reaction of δ- and ε-keto esters of 1,1′-binaphthalen-2-ols with an oligoether tether as the 2′-substituent: Application to the synthesis of (-)-malyngolide

, p. 645 - 653 (2007/10/03)

Efficient 1,8- and 1,9-asymmetric inductions in the Grignard reaction of podand-type δ- (3,4) and ε-keto esters (5,6) are achieved in the presence of MgBr2·OEt2 with up to 97 and 82% optical yields, respectively, by using 2′-[3-(2-methoxyethoxy)propoxy]-1,1′-binaphthalen-2-ol as the chiral auxiliary. The 1,8-asymmetric inductive Grignard reaction has been advantageously utilized in the key step of a synthesis of (-)-malyngolide.
