427888-22-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 427888-22-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,7,8,8 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 427888-22:
(8*4)+(7*2)+(6*7)+(5*8)+(4*8)+(3*8)+(2*2)+(1*2)=190
190 % 10 = 0
So 427888-22-0 is a valid CAS Registry Number.
