218145-23-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 218145-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,1,4 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 218145-23:
(8*2)+(7*1)+(6*8)+(5*1)+(4*4)+(3*5)+(2*2)+(1*3)=114
114 % 10 = 4
So 218145-23-4 is a valid CAS Registry Number.
