69799-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69799-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,7,9 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 69799-33:
(7*6)+(6*9)+(5*7)+(4*9)+(3*9)+(2*3)+(1*3)=203
203 % 10 = 3
So 69799-33-3 is a valid CAS Registry Number.
