218783-81-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 218783-81-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,7,8 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 218783-81:
(8*2)+(7*1)+(6*8)+(5*7)+(4*8)+(3*3)+(2*8)+(1*1)=164
164 % 10 = 4
So 218783-81-4 is a valid CAS Registry Number.
