34133-56-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34133-56-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,1,3 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 34133-56:
(7*3)+(6*4)+(5*1)+(4*3)+(3*3)+(2*5)+(1*6)=87
87 % 10 = 7
So 34133-56-7 is a valid CAS Registry Number.
