133536-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133536-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,3 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133536-28:
(8*1)+(7*3)+(6*3)+(5*5)+(4*3)+(3*6)+(2*2)+(1*8)=114
114 % 10 = 4
So 133536-28-4 is a valid CAS Registry Number.
