133809-56-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133809-56-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,0 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133809-56:
(8*1)+(7*3)+(6*3)+(5*8)+(4*0)+(3*9)+(2*5)+(1*6)=130
130 % 10 = 0
So 133809-56-0 is a valid CAS Registry Number.
