104690-23-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104690-23-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,9 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 104690-23:
(8*1)+(7*0)+(6*4)+(5*6)+(4*9)+(3*0)+(2*2)+(1*3)=105
105 % 10 = 5
So 104690-23-5 is a valid CAS Registry Number.
