69988-36-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69988-36-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,8 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 69988-36:
(7*6)+(6*9)+(5*9)+(4*8)+(3*8)+(2*3)+(1*6)=209
209 % 10 = 9
So 69988-36-9 is a valid CAS Registry Number.
