69097-21-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69097-21-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,0,9 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 69097-21:
(7*6)+(6*9)+(5*0)+(4*9)+(3*7)+(2*2)+(1*1)=158
158 % 10 = 8
So 69097-21-8 is a valid CAS Registry Number.
