138969-05-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138969-05-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,6 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138969-05:
(8*1)+(7*3)+(6*8)+(5*9)+(4*6)+(3*9)+(2*0)+(1*5)=178
178 % 10 = 8
So 138969-05-8 is a valid CAS Registry Number.
