Definition
ChEBI: A benzenedicarboxamide compound having N-substituted carbamoyl groups at the 1- and 3-positions, iodo substituents at the 2-, 4- and 6-positions and a 3-hydroxy-2-(hydroxymethyl)propanimido at position 5.
Check Digit Verification of cas no
The CAS Registry Mumber 136949-58-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,4 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 136949-58:
(8*1)+(7*3)+(6*6)+(5*9)+(4*4)+(3*9)+(2*5)+(1*8)=171
171 % 10 = 1
So 136949-58-1 is a valid CAS Registry Number.
