139427-35-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139427-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,2 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139427-35:
(8*1)+(7*3)+(6*9)+(5*4)+(4*2)+(3*7)+(2*3)+(1*5)=143
143 % 10 = 3
So 139427-35-3 is a valid CAS Registry Number.
