1228187-59-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1228187-59-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,1,8 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1228187-59:
(9*1)+(8*2)+(7*2)+(6*8)+(5*1)+(4*8)+(3*7)+(2*5)+(1*9)=164
164 % 10 = 4
So 1228187-59-4 is a valid CAS Registry Number.
