124765-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124765-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,7,6 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 124765-40:
(8*1)+(7*2)+(6*4)+(5*7)+(4*6)+(3*5)+(2*4)+(1*0)=128
128 % 10 = 8
So 124765-40-8 is a valid CAS Registry Number.
