124678-35-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124678-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,6,7 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 124678-35:
(8*1)+(7*2)+(6*4)+(5*6)+(4*7)+(3*8)+(2*3)+(1*5)=139
139 % 10 = 9
So 124678-35-9 is a valid CAS Registry Number.
