69310-18-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69310-18-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,3,1 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 69310-18:
(7*6)+(6*9)+(5*3)+(4*1)+(3*0)+(2*1)+(1*8)=125
125 % 10 = 5
So 69310-18-5 is a valid CAS Registry Number.
