890100-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 890100-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,1,0 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 890100-69:
(8*8)+(7*9)+(6*0)+(5*1)+(4*0)+(3*0)+(2*6)+(1*9)=153
153 % 10 = 3
So 890100-69-3 is a valid CAS Registry Number.
