51489-23-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51489-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,4,8 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 51489-23:
(7*5)+(6*1)+(5*4)+(4*8)+(3*9)+(2*2)+(1*3)=127
127 % 10 = 7
So 51489-23-7 is a valid CAS Registry Number.
