126569-45-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126569-45-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,6 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 126569-45:
(8*1)+(7*2)+(6*6)+(5*5)+(4*6)+(3*9)+(2*4)+(1*5)=147
147 % 10 = 7
So 126569-45-7 is a valid CAS Registry Number.
