187981-04-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 187981-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,9,8 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 187981-04:
(8*1)+(7*8)+(6*7)+(5*9)+(4*8)+(3*1)+(2*0)+(1*4)=190
190 % 10 = 0
So 187981-04-0 is a valid CAS Registry Number.

Rational design of Mn-salen catalyst (2): Highly enantioselective epoxidation of conjugated cis-olefins

Sasaki,Irie,Hamada,Suzuki,Katsuki

, p. 11827 - 11838 (1994)

On the basis of the newly proposed hypothesis on the mechanism of asymmetric induction, highly efficient (salen)mangenese(III) complex (3) was constructed as a catalyst for asymmetric epoxidation. With this catalyst, the highest level of enantioselectivit
