124476-91-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124476-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,4,7 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 124476-91:
(8*1)+(7*2)+(6*4)+(5*4)+(4*7)+(3*6)+(2*9)+(1*1)=131
131 % 10 = 1
So 124476-91-1 is a valid CAS Registry Number.
