268556-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 268556-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,8,5,5 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 268556-63:
(8*2)+(7*6)+(6*8)+(5*5)+(4*5)+(3*6)+(2*6)+(1*3)=184
184 % 10 = 4
So 268556-63-4 is a valid CAS Registry Number.
