Check Digit Verification of cas no

The CAS Registry Mumber 129661-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,6,6 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129661-25:
(8*1)+(7*2)+(6*9)+(5*6)+(4*6)+(3*1)+(2*2)+(1*5)=142
142 % 10 = 2
So 129661-25-2 is a valid CAS Registry Number.

One-Pot Oxapropellane Skeleton Formation Based on Conjugate Addition

Fang, Chenglin,Suganuma, Kyoko,Suemune, Hiroshi,Sakai, Kiyoshi

, p. 1549 - 1554 (2007/10/02)

Reactions of five- and/or six-membered-ring ketones 1-5 possessing an ω-halogenoalkyl group and α',β'-unsaturated ester function at the α-position with diorganocuprates afforded the oxapropellane compounds 20-24 in a one-pot, three-step procedure via 1,4-

One-pot Construction of the Oxapropellane Skeleton

Fang, Chenglin,Suganuma, Kyoko,Suemune, Hiroshi,Sakai, Kiyoshi

, p. 1483 - 1484 (2007/10/02)

1,4-Addition of diorganocuprates to the α,β-unsaturated esters (1)-(5) gave the oxapropellane skeleton, compounds (6)-(10), in a one-pot reaction, which proceeded via 1,4-addition, aldol condensation, and substitution.
