139367-90-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139367-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,6 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139367-90:
(8*1)+(7*3)+(6*9)+(5*3)+(4*6)+(3*7)+(2*9)+(1*0)=161
161 % 10 = 1
So 139367-90-1 is a valid CAS Registry Number.
