134252-17-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134252-17-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,5 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134252-17:
(8*1)+(7*3)+(6*4)+(5*2)+(4*5)+(3*2)+(2*1)+(1*7)=98
98 % 10 = 8
So 134252-17-8 is a valid CAS Registry Number.
