39806-23-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39806-23-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,8,0 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 39806-23:
(7*3)+(6*9)+(5*8)+(4*0)+(3*6)+(2*2)+(1*3)=140
140 % 10 = 0
So 39806-23-0 is a valid CAS Registry Number.

Telluro-directed regiospecific and highly stereoselective reaction of ethyl 5-telluro-(2E,4Z)-pentadienoate with organocopper reagents

Huang, Yao-Zeng,Mo, Xue-Sheng,Wang, Lei

, p. 419 - 422 (1998)

Ethyl 5-telluro-(2E,4Z)-pentadienoate 2, which is prepared by the Wittig olefination of (Z)-β-telluroacrolein 1, reacted very rapidly with organocuprates 3 at -78°C to form exclusively the corresponding 5-substituted products 4 with high stereoselectivity
