129133-55-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129133-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,3 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129133-55:
(8*1)+(7*2)+(6*9)+(5*1)+(4*3)+(3*3)+(2*5)+(1*5)=117
117 % 10 = 7
So 129133-55-7 is a valid CAS Registry Number.
