Check Digit Verification of cas no
The CAS Registry Mumber 121224-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,2,2 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121224-75:
(8*1)+(7*2)+(6*1)+(5*2)+(4*2)+(3*4)+(2*7)+(1*5)=77
77 % 10 = 7
So 121224-75-7 is a valid CAS Registry Number.

NICKEL-CATALYZED INTRAMOLECULAR ALLYLATION OF ALKENES AND ALKYNES COUPLED WITH β-ELIMINATION OR CARBONYLATION
Oppolzer, Wolfgang,Bedoya-Zurita, Manuel,Switzer, Christopher Y.
, p. 6433 - 6436 (1988)
Intramolecular allylations, combined with either β-eliminations (1 -> 2) or carbonylations (10 -> 12 + 13, 14 -> 16 and 17 -> 19 + 20) were catalyzed by Pt(PPh3)4, Ni(COD)/dppb, or Ni(CO)3PPh3, respectively.
