803683-54-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 803683-54-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,3,6,8 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 803683-54:
(8*8)+(7*0)+(6*3)+(5*6)+(4*8)+(3*3)+(2*5)+(1*4)=167
167 % 10 = 7
So 803683-54-7 is a valid CAS Registry Number.

Asymmetric iodolactamization induced by chiral oxazolidine auxiliary
Shen, Meihua,Li, Chaozhong
, p. 7906 - 7909 (2007/10/03)
Asymmetric iodolactamization reactions of unsaturated amides with oxazolidines as the chiral auxiliaries were investigated. With (4S)-4-((2R)-2-butyl)-2,2-dimethyloxazolidine as the auxiliary and LiH as the base, a number of unsaturated amides underwent i
