133038-85-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133038-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,3 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133038-85:
(8*1)+(7*3)+(6*3)+(5*0)+(4*3)+(3*8)+(2*8)+(1*5)=104
104 % 10 = 4
So 133038-85-4 is a valid CAS Registry Number.
