133306-24-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133306-24-8 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 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 133306-24:
(8*1)+(7*3)+(6*3)+(5*3)+(4*0)+(3*6)+(2*2)+(1*4)=88
88 % 10 = 8
So 133306-24-8 is a valid CAS Registry Number.
