133074-67-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133074-67-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,7 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133074-67:
(8*1)+(7*3)+(6*3)+(5*0)+(4*7)+(3*4)+(2*6)+(1*7)=106
106 % 10 = 6
So 133074-67-6 is a valid CAS Registry Number.
