Check Digit Verification of cas no

The CAS Registry Mumber 194544-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,5,4 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 194544-20:
(8*1)+(7*9)+(6*4)+(5*5)+(4*4)+(3*4)+(2*2)+(1*0)=152
152 % 10 = 2
So 194544-20-2 is a valid CAS Registry Number.

Haem d1: Stereoselective synthesis of the macrocycle to establish its absolute configuration as 2R,7R

Micklefield, Jason,Beckmann, Marion,Mackman, Richard L.,Block, Michael H.,Leeper, Finian J.,Battersby, Alan R.

, p. 2123 - 2138 (2007/10/03)

Although the gross structure of haem d1 1 has been established, the absolute stereochemistry at C-2 and C-7 is unknown. An unambiguous stereoselective synthesis of the ester of the metal-free macrocycle corresponding to haem d1 has b

A Novel Stereoselective Synthesis of the Macrocycle of Haem d1 that establishes its Absolute Configuration as 2R,7R

Micklefield, Jason,Mackman, Richard L.,Aucken, Christopher J.,Beckmann, Marion,Block, Michael H.,et al.

, p. 275 - 277 (2007/10/02)

A novel route to isobacteriochlorins is developed that allows the stereoselective synthesis of the macrocycle of haem d1 and so establishes its absolute configuration 2R,7R.
