Check Digit Verification of cas no

The CAS Registry Mumber 881099-32-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,0,9 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 881099-32:
(8*8)+(7*8)+(6*1)+(5*0)+(4*9)+(3*9)+(2*3)+(1*2)=197

New utilizations of optically active homoallylamines: Highly stereoselective synthesis of cyclic guanidine and thiourea

Yanada, Reiko,Kaieda, Akira,Yanada, Kazuo,Takemoto, Yoshiji

, p. 101 - 106 (2007/10/03)

Halocyclizations of optically active homoallylguanidine and homoallylthiourea were examined. These reactions proceeded stereoselectively to give six membered cyclic guanidines and thiourea. High 1,3-asymmetric induction by the homoallylic substituents is
