1152781-31-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1152781-31-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,2,7,8 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1152781-31:
(9*1)+(8*1)+(7*5)+(6*2)+(5*7)+(4*8)+(3*1)+(2*3)+(1*1)=141
141 % 10 = 1
So 1152781-31-1 is a valid CAS Registry Number.

Enantioselective synthesis of (R)-tolterodine via CuH-catalyzed asymmetric conjugate reduction
Yoo, Kihyun,Kim, Hyohyun,Yun, Jaesook
, p. 4232 - 4235 (2009)
(Chemical Equation Presented) An efficient and highly enantioselective method for the preparation of (R)-tolterodine is described. The synthesis was performed by CuH-catalyzed asymmetric conjugate reduction of a β,β-diaryl-substituted unsaturated nitrile
