129201-41-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129201-41-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,0 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129201-41:
(8*1)+(7*2)+(6*9)+(5*2)+(4*0)+(3*1)+(2*4)+(1*1)=98
98 % 10 = 8
So 129201-41-8 is a valid CAS Registry Number.

ENANTIOSELECTIVE SYNTHESIS VIA THE NUCLEOPHILIC ALKYLATION OF HYDRAZONES: ACETALS AS CHIRAL AUXILIARIES
Thiam, Mohamadou,Chastrette, Francine
, p. 1429 - 1432 (2007/10/02)
Diastereoselective addition of organolithium reagents on hydrazones vicinal to chiral cyclic acetals provide chiral hydrazinoacetals from which optically active aminoacetals and aminoacids can be prepared.
