155536-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155536-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,5,3 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 155536-77:
(8*1)+(7*5)+(6*5)+(5*5)+(4*3)+(3*6)+(2*7)+(1*7)=149
149 % 10 = 9
So 155536-77-9 is a valid CAS Registry Number.

, p. 759 - 766 (2007/10/02)
The new dithiametacyclophane 3c and the thiaazametacyclophanes 6a, b are chiral, but do not contain chirality centres.They are obtained by cyclization of 1,3-propanedithiol (2), or of the thiaza precursors 5a, b, with the bis(bromomethyl) compounds 1, 4a,
