69922-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69922-33-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,2 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 69922-33:
(7*6)+(6*9)+(5*9)+(4*2)+(3*2)+(2*3)+(1*3)=164
164 % 10 = 4
So 69922-33-4 is a valid CAS Registry Number.
