346620-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 346620-69-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,6,6,2 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 346620-69:
(8*3)+(7*4)+(6*6)+(5*6)+(4*2)+(3*0)+(2*6)+(1*9)=147
147 % 10 = 7
So 346620-69-7 is a valid CAS Registry Number.
