Check Digit Verification of cas no

The CAS Registry Mumber 128260-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,6 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128260-82:
(8*1)+(7*2)+(6*8)+(5*2)+(4*6)+(3*0)+(2*8)+(1*2)=122
122 % 10 = 2
So 128260-82-2 is a valid CAS Registry Number.

A short and efficient enantioselective route to a key intermediate for the total synthesis of forskolin

Corey,Da Silva Jardine

, p. 7297 - 7300 (2007/10/02)

A simple route for the enantioselective synthesis of key intermediates (11 and 12) for the total synthesis of forskolin has been developed starting from acid 6 and (S)-alcohol 5. The latter is prepared by enantioselective catalytic CBS reduction of dienon
