133374-67-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133374-67-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,7 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133374-67:
(8*1)+(7*3)+(6*3)+(5*3)+(4*7)+(3*4)+(2*6)+(1*7)=121
121 % 10 = 1
So 133374-67-1 is a valid CAS Registry Number.
