Check Digit Verification of cas no

The CAS Registry Mumber 1228274-07-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,2,7 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1228274-07:
(9*1)+(8*2)+(7*2)+(6*8)+(5*2)+(4*7)+(3*4)+(2*0)+(1*7)=144
144 % 10 = 4
So 1228274-07-4 is a valid CAS Registry Number.

Enantioselective synthesis of (+)-isolysergol via ring-closing metathesis

Deck, Jason A.,Martin, Stephen F.

supporting information; experimental part, p. 2610 - 2613 (2010/08/19)

The first enantioselective synthesis of (+)-isolysergol was completed in 12 steps from commercially available materials by a novel approach that features a late stage microwave-mediated, diastereomeric ring-closing metathesis catalyzed by a chiral molybdenum catalyst to simultaneously form the D ring and set the stereocenter at C(8).
