98006-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98006-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,0 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 98006-20:
(7*9)+(6*8)+(5*0)+(4*0)+(3*6)+(2*2)+(1*0)=133
133 % 10 = 3
So 98006-20-3 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.
