1426841-47-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1426841-47-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,8,4 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1426841-47:
(9*1)+(8*4)+(7*2)+(6*6)+(5*8)+(4*4)+(3*1)+(2*4)+(1*7)=165
165 % 10 = 5
So 1426841-47-5 is a valid CAS Registry Number.
