133308-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133308-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,0 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133308-56:
(8*1)+(7*3)+(6*3)+(5*3)+(4*0)+(3*8)+(2*5)+(1*6)=102
102 % 10 = 2
So 133308-56-2 is a valid CAS Registry Number.
