Check Digit Verification of cas no

The CAS Registry Mumber 1304513-91-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,4,5,1 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1304513-91:
(9*1)+(8*3)+(7*0)+(6*4)+(5*5)+(4*1)+(3*3)+(2*9)+(1*1)=114
114 % 10 = 4
So 1304513-91-4 is a valid CAS Registry Number.

Synthesis of ginkgolic acid analogues and evaluation of their molluscicidal activity

Zhang, Peng,Pan, Jiahu,Duan, Wanxing,Li, Xuedong,Zhang, Yao,Zhou, Yibiao,Jiang, Qingwu,Mao, Zuohua,Yu, Peizhong

experimental part, p. 4059 - 4069 (2011/07/07)

Based on the molluscicidal activity of ginkgolic acids (GAs) isolated from Ginkgo biloba L, a series of Z/E isomers of GA analogues were prepared and evaluated for their molluscicidal activities against the host snail Oncomelania hupensis. The results and analysis of the structure-activity relationship revealed that the E-isomers showed better molluscicidal activities than their Z-isomers. Molluscicidal activities decreased with the shortening of the alkenyl chain lengths.
