75781-75-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75781-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,7,8 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 75781-75:
(7*7)+(6*5)+(5*7)+(4*8)+(3*1)+(2*7)+(1*5)=168
168 % 10 = 8
So 75781-75-8 is a valid CAS Registry Number.

Regiochemical Control in the Alkylation of Tetrahydroindanones
Lee, Thomas V.,Toczek, Judy
, p. 759 - 762 (2007/10/02)
The first regiospecific alkylation of the 3a,4,7,7a-tetrahydroindanone (1) has been achieved, by use of a phenylthio group acting as a directing group for enolate anion generation or as a blocking group which permits the formation of the regioisomeric eno
