139697-01-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139697-01-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,9 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139697-01:
(8*1)+(7*3)+(6*9)+(5*6)+(4*9)+(3*7)+(2*0)+(1*1)=171
171 % 10 = 1
So 139697-01-1 is a valid CAS Registry Number.
