346687-24-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 346687-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,6,6,8 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 346687-24:
(8*3)+(7*4)+(6*6)+(5*6)+(4*8)+(3*7)+(2*2)+(1*4)=179
179 % 10 = 9
So 346687-24-9 is a valid CAS Registry Number.
