133901-49-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133901-49-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,0 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133901-49:
(8*1)+(7*3)+(6*3)+(5*9)+(4*0)+(3*1)+(2*4)+(1*9)=112
112 % 10 = 2
So 133901-49-2 is a valid CAS Registry Number.
