Check Digit Verification of cas no

The CAS Registry Mumber 803699-27-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,3,6,9 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 803699-27:
(8*8)+(7*0)+(6*3)+(5*6)+(4*9)+(3*9)+(2*2)+(1*7)=186
186 % 10 = 6
So 803699-27-6 is a valid CAS Registry Number.

Double stereodifferentiating aldol reactions based on chiral ketones derived from lactic acid: Synthesis of C1-C6 fragment of erythronolides

Solsona, Joan G.,Nebot, Joaquim,Romea, Pedro,Urpí, Fèlix

, p. 2127 - 2130 (2007/10/03)

Highly stereoselective titanium-mediated aldol additions of ethyl ketones derived from lactic acid to α-methyl-β-OTBDPS chiral aldehydes are documented. One of these double stereodifferentiating processes represents the key step of a straightforward and e
