Check Digit Verification of cas no

The CAS Registry Mumber 1235989-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,5,9,8 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1235989-52:
(9*1)+(8*2)+(7*3)+(6*5)+(5*9)+(4*8)+(3*9)+(2*5)+(1*2)=192
192 % 10 = 2
So 1235989-52-2 is a valid CAS Registry Number.

Synthesis of norcantharidin-dimer derivatives

Deng, Liping,Yong, Zhang,Tao, Weifeng,Shen, Jianfeng,Wang, Wei

experimental part, p. 158 - 161 (2011/04/16)

We use one molecule of ethylene diamine as a connecting arm to combine two molecules of 5,6-dehydronorcantharidin. Then, ten novel norcantharidin derivatives were synthesized in a single step by the [3 + 2] 1,3-dipolar cycloaddition reaction with oxime or hydrazone in the presence of chloramine-T, which is simpler than the conventional method.
