Check Digit Verification of cas no

The CAS Registry Mumber 16416-41-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,1 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16416-41:
(7*1)+(6*6)+(5*4)+(4*1)+(3*6)+(2*4)+(1*1)=94
94 % 10 = 4
So 16416-41-4 is a valid CAS Registry Number.

Chiral Organometallic Reagents, IV Stereoselective Formation of β-Silyloxy-α-bromoalkyllithium Compounds

Hoffmann, Reinhard W.,Julius, Manfred

, p. 811 - 822 (2007/10/02)

The diastereomeric carbenoids 4 have been generated by diastereoselective (84:16) exchange of the diastereotopic bromine atoms in the dibromo compound 3 for lithium at -120 deg C.The implication of the observed diastereoselectivity for the Nozaki ring-expansion method is discussedKey words: Carbenoids / Halogen-metal exchange / Diastereotopic groups
