227754-48-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 227754-48-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,7,5 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 227754-48:
(8*2)+(7*2)+(6*7)+(5*7)+(4*5)+(3*4)+(2*4)+(1*8)=155
155 % 10 = 5
So 227754-48-5 is a valid CAS Registry Number.
