132629-67-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132629-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,6,2 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132629-67:
(8*1)+(7*3)+(6*2)+(5*6)+(4*2)+(3*9)+(2*6)+(1*7)=125
125 % 10 = 5
So 132629-67-5 is a valid CAS Registry Number.
