6629-33-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6629-33-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,2 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6629-33:
(6*6)+(5*6)+(4*2)+(3*9)+(2*3)+(1*3)=110
110 % 10 = 0
So 6629-33-0 is a valid CAS Registry Number.
