65621-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65621-33-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,6,2 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 65621-33:
(7*6)+(6*5)+(5*6)+(4*2)+(3*1)+(2*3)+(1*3)=122
122 % 10 = 2
So 65621-33-2 is a valid CAS Registry Number.
