Check Digit Verification of cas no

The CAS Registry Mumber 118977-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,9,7 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118977-90:
(8*1)+(7*1)+(6*8)+(5*9)+(4*7)+(3*7)+(2*9)+(1*0)=175
175 % 10 = 5
So 118977-90-5 is a valid CAS Registry Number.

Chemistry of tricarbonyl hemiketals and application of Evans' technology to the total synthesis of the immunosuppressant (-)-FK-506

Jones,Reamer,Desmond,Mills

, p. 2998 - 3017 (2007/10/02)

Details of model studies probing the chemistry of the tricarbonyl region of FK-506 are presented, and their use in designing a successful route to this immunosuppressant is outlined. Application of asymmetric oxazolidinone alkylation/aldol methodology to a convergent, highly flexible synthesis of the C10-C18 fragment and to improvements in the preparation of the C20-C34 segment are also discussed.
