134347-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134347-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,3,4 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134347-99:
(8*1)+(7*3)+(6*4)+(5*3)+(4*4)+(3*7)+(2*9)+(1*9)=132
132 % 10 = 2
So 134347-99-2 is a valid CAS Registry Number.
