Check Digit Verification of cas no

The CAS Registry Mumber 221290-72-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,2,9 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 221290-72:
(8*2)+(7*2)+(6*1)+(5*2)+(4*9)+(3*0)+(2*7)+(1*2)=98
98 % 10 = 8
So 221290-72-8 is a valid CAS Registry Number.

Synthetic studies on the sarcodictyins: Synthesis of fully functionalized cyclization precursors

Ceccarelli, Simona M,Piarulli, Umberto,Gennari, Cesare

, p. 8531 - 8542 (2007/10/03)

A strategy featuring a key retrosynthetic disconnection at the C2-C3 position was applied to the total synthesis of the common diterpenoid tricyclic skeleton of sarcodictyins and eleutherobin. Fully functionalized cyclization precursors were accessed via a brief and convergent route, making use of unprecedented synthetic transformations.

Synthetic studies on sarcodictyins and eleutherobin: Synthesis of fully functionalized cyclization precursors

Ceccarelli, Simona,Piarulli, Umberto,Gennari, Cesare

, p. 153 - 156 (2007/10/03)

Unprecedented synthetic transformations were demonstrated during the preparation of fully functionalized cyclization precursors of type 2, in a synthetic approach to sarcodictyin A and B (1a,b) and eleutherobin (1c).
