134720-06-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134720-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,7,2 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 134720-06:
(8*1)+(7*3)+(6*4)+(5*7)+(4*2)+(3*0)+(2*0)+(1*6)=102
102 % 10 = 2
So 134720-06-2 is a valid CAS Registry Number.
