1228268-23-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1228268-23-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,2,6 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1228268-23:
(9*1)+(8*2)+(7*2)+(6*8)+(5*2)+(4*6)+(3*8)+(2*2)+(1*3)=152
152 % 10 = 2
So 1228268-23-2 is a valid CAS Registry Number.
