347367-55-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 347367-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,7,3,6 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 347367-55:
(8*3)+(7*4)+(6*7)+(5*3)+(4*6)+(3*7)+(2*5)+(1*5)=169
169 % 10 = 9
So 347367-55-9 is a valid CAS Registry Number.
