111698-64-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111698-64-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,6,9 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 111698-64:
(8*1)+(7*1)+(6*1)+(5*6)+(4*9)+(3*8)+(2*6)+(1*4)=127
127 % 10 = 7
So 111698-64-7 is a valid CAS Registry Number.

ENANTIOSPECIFIC SYNTHESIS OF ESTRONE
Hutchinson, John H.,Money, Thomas
, p. 1 - 6 (2007/10/02)
Efiicient cleavage of the C(1)-C(2) bond in 9,10-dibromocamphor (3) provides a chiral intermediate (5) that can be used in a new enantiospecific synthesis of estrone.
