697803-44-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 697803-44-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,7,8,0 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 697803-44:
(8*6)+(7*9)+(6*7)+(5*8)+(4*0)+(3*3)+(2*4)+(1*4)=214
214 % 10 = 4
So 697803-44-4 is a valid CAS Registry Number.

CN-assisted oxidative cyclization of cyano cinnamates and styrene derivatives: A facile entry to 3-substituted chiral phthalides

Reddy, R.Santhosh,Kiran, I. N. Chaithanya,Sudalai, Arumugam

supporting information; experimental part, p. 3655 - 3661 (2012/05/31)

The asymmetric dihydroxylation (AD) of o-cyano cinnamates and styrene derivatives leads to efficient construction of chiral phthalide frameworks in high optical purities. This unique reaction is characterized by unusual synergism between CN and osmate groups resulting in rate enhancement of the AD process. The method is amply demonstrated by the synthesis and the structural/stereochemical assignment of the natural products.
