Check Digit Verification of cas no

The CAS Registry Mumber 1239279-12-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,2,7 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1239279-12:
(9*1)+(8*2)+(7*3)+(6*9)+(5*2)+(4*7)+(3*9)+(2*1)+(1*2)=169
169 % 10 = 9
So 1239279-12-9 is a valid CAS Registry Number.

Efficient enzymatic kinetic resolution of 2-heptylamine with a highly active acyl donor

Sun, Jian-Hua,Dai, Rong-Ji,Meng, Wei-Wei,Deng, Yu-Lin

, p. 987 - 991 (2010)

Novozyme435 facilitated kinetic resolution of 2-heptylamine was here presented. Methyl methoxyacetate was used as acyl donor. A survey of influencing factors including hydrogen bonding effect, solvent effect, steric effect, temperature and the amount of acyl donor were investigated in detail. At the optimum conditions, the enantiomeric separation was successfully obtained within 8 h at 20 °C, and gave high conversion and optical purity of (R)-2-heptylamine, 48.9% and over 99% respectively. The immobilized lipase B was found to be suitable for the enantiomeric separation of aliphatic amines with good recyclability.
