345894-61-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 345894-61-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,5,8,9 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 345894-61:
(8*3)+(7*4)+(6*5)+(5*8)+(4*9)+(3*4)+(2*6)+(1*1)=183
183 % 10 = 3
So 345894-61-3 is a valid CAS Registry Number.
