91406-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91406-90-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,4,0 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91406-90:
(7*9)+(6*1)+(5*4)+(4*0)+(3*6)+(2*9)+(1*0)=125
125 % 10 = 5
So 91406-90-5 is a valid CAS Registry Number.
