126537-87-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126537-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,3 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 126537-87:
(8*1)+(7*2)+(6*6)+(5*5)+(4*3)+(3*7)+(2*8)+(1*7)=139
139 % 10 = 9
So 126537-87-9 is a valid CAS Registry Number.
