Check Digit Verification of cas no

The CAS Registry Mumber 180979-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,9,7 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 180979-41:
(8*1)+(7*8)+(6*0)+(5*9)+(4*7)+(3*9)+(2*4)+(1*1)=173
173 % 10 = 3
So 180979-41-3 is a valid CAS Registry Number.

Enantioselective Syntheses of (–)-Alloyohimbane and (–)-Yohimbane by an Efficient Enzymatic Desymmetrization Process

Ghosh, Arun K.,Sarkar, Anindya

, p. 6001 - 6009 (2016/12/26)

Enantioselective syntheses of (–)-alloyohimbane and (–)-yohimbane were accomplished in a convergent manner. The key step involves a modified mild protocol for the enantioselective enzymatic desymmetrization of a meso-diacetate. This provides convenient access to an optically active monoacetate in multi-gram quantities and in high enantiomeric purity. This monoacetate was converted to (–)-alloyohimbane. Reductive amination of the derived aldehyde caused isomerization to the trans-product and, ultimately, the formation of (–)-yohimbane.
