139371-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139371-63-4 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 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139371-63:
(8*1)+(7*3)+(6*9)+(5*3)+(4*7)+(3*1)+(2*6)+(1*3)=144
144 % 10 = 4
So 139371-63-4 is a valid CAS Registry Number.
