Check Digit Verification of cas no

The CAS Registry Mumber 1359876-09-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,9,8,7 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1359876-09:
(9*1)+(8*3)+(7*5)+(6*9)+(5*8)+(4*7)+(3*6)+(2*0)+(1*9)=217
217 % 10 = 7
So 1359876-09-7 is a valid CAS Registry Number.

Regioselective ring expansion of 2,4-diiminoazetidines via cleavage of C-N and C(sp3)-H bonds: Efficient construction of 2,3- dihydropyrimidinesulfonamides

Wang, Yang,Chi, Yue,Zhang, Wen-Xiong,Xi, Zhenfeng

supporting information; experimental part, p. 2926 - 2929 (2012/03/27)

A highly regioselective base-mediated ring expansion of 2,4-diiminoazetidines via cleavage of C-N and C(sp3)-H bonds is achieved for the first time to afford efficiently 2,3- dihydropyrimidinesulfonamides. The mechanism of the ring expansion via tandem 4π electrocyclic ring-opening/1,5-H shift/6π electrocyclic ring-closing is well confirmed by the trapping experiments of two key intermediates and deuterium labeling studies.
