Check Digit Verification of cas no
The CAS Registry Mumber 180320-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,3,2 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180320-55:
(8*1)+(7*8)+(6*0)+(5*3)+(4*2)+(3*0)+(2*5)+(1*5)=102
102 % 10 = 2
So 180320-55-2 is a valid CAS Registry Number.

Synthesis of SB 222618. A potential PDE IV inhibitor
Conde, Jose J.,Mendelson, Wilford
, p. 811 - 814 (2000)
PDE IV inhibitor SB 222618 was prepared by regioselective S(N)2' addition of 9 to bromoallene 6a followed by a stereoselective borane reduction of 4 to afford 2 which by a palladium mediated coupling with 3, delivered SB 222618 (1) in good yield. (C) 2000 Elsevier Science Ltd.
