Check Digit Verification of cas no
The CAS Registry Mumber 137617-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,1 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137617-65:
(8*1)+(7*3)+(6*7)+(5*6)+(4*1)+(3*7)+(2*6)+(1*5)=143

Yamamoto, Yoshinori,Okano, Hiroshi,Yamada, Jun-ichi
, p. 4749 - 4752 (2007/10/02)
The reaction of Ge-masked dienolates with Michael acceptors in the presence of Lewis acids produced the 1,4-γ adduct regioselectively, whereas the reaction in the presence of Bu4NF gave the 1,4-α adduct exclusively
