139685-58-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139685-58-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,8 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139685-58:
(8*1)+(7*3)+(6*9)+(5*6)+(4*8)+(3*5)+(2*5)+(1*8)=178
178 % 10 = 8
So 139685-58-8 is a valid CAS Registry Number.
