67652-33-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67652-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,5 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67652-33:
(7*6)+(6*7)+(5*6)+(4*5)+(3*2)+(2*3)+(1*3)=149
149 % 10 = 9
So 67652-33-9 is a valid CAS Registry Number.
