139374-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139374-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,7 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139374-22:
(8*1)+(7*3)+(6*9)+(5*3)+(4*7)+(3*4)+(2*2)+(1*2)=144
144 % 10 = 4
So 139374-22-4 is a valid CAS Registry Number.
