268750-55-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 268750-55-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,8,7,5 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 268750-55:
(8*2)+(7*6)+(6*8)+(5*7)+(4*5)+(3*0)+(2*5)+(1*5)=176
176 % 10 = 6
So 268750-55-6 is a valid CAS Registry Number.
