264283-42-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 264283-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,4,2,8 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 264283-42:
(8*2)+(7*6)+(6*4)+(5*2)+(4*8)+(3*3)+(2*4)+(1*2)=143
143 % 10 = 3
So 264283-42-3 is a valid CAS Registry Number.
