69565-90-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69565-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,6 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69565-90:
(7*6)+(6*9)+(5*5)+(4*6)+(3*5)+(2*9)+(1*0)=178
178 % 10 = 8
So 69565-90-8 is a valid CAS Registry Number.
