Check Digit Verification of cas no

The CAS Registry Mumber 1377313-89-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,7,3,1 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1377313-89:
(9*1)+(8*3)+(7*7)+(6*7)+(5*3)+(4*1)+(3*3)+(2*8)+(1*9)=177
177 % 10 = 7
So 1377313-89-7 is a valid CAS Registry Number.

Intramolecular methylation of an allyl sulfone via lithium alkoxyaluminate; Application to the enantioselective synthesis of the CD ring of vitamin D 3

Sikervar, Vikas,Fuchs, Philip L.

supporting information; experimental part, p. 2922 - 2924 (2012/07/28)

Alcohol-directed intramolecular methylation of an enantiopure allyl sulfone using AlMe3 provides a trans-hydrindane CD ring alcohol. The substrate cis-CD ring allyl sulfone alcohol is prepared via intramolecular allyl sulfonyl anion addition to aldehyde using Ba(OH)2.
