30609-33-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 30609-33-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,6,0 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 30609-33:
(7*3)+(6*0)+(5*6)+(4*0)+(3*9)+(2*3)+(1*3)=87
87 % 10 = 7
So 30609-33-7 is a valid CAS Registry Number.
