127056-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127056-76-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,5 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 127056-76:
(8*1)+(7*2)+(6*7)+(5*0)+(4*5)+(3*6)+(2*7)+(1*6)=122
122 % 10 = 2
So 127056-76-2 is a valid CAS Registry Number.

Dimerization of Pyrazolyl-5-hydroxypyrrolidinones to Tetrazocines
Brinkmeyer, Raymond S.,Terando, Norman H.
, p. 1713 - 1717 (2007/10/02)
The dimerization of the hydroxypyrrolidinones 5 and 9 yield the tetrazocines 8 and 11.In addition, in the case of compound 9, the ring-fused hexaazacyclododecane 12 was isolated.X-ray diffraction analysis of compound 11 verified the dimeric structure of these products.
