104607-90-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104607-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,0 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 104607-90:
(8*1)+(7*0)+(6*4)+(5*6)+(4*0)+(3*7)+(2*9)+(1*0)=101
101 % 10 = 1
So 104607-90-1 is a valid CAS Registry Number.
