228396-01-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 228396-01-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,3,9 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 228396-01:
(8*2)+(7*2)+(6*8)+(5*3)+(4*9)+(3*6)+(2*0)+(1*1)=148
148 % 10 = 8
So 228396-01-8 is a valid CAS Registry Number.
