126827-25-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 126827-25-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,8,2 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 126827-25:
(8*1)+(7*2)+(6*6)+(5*8)+(4*2)+(3*7)+(2*2)+(1*5)=136
136 % 10 = 6
So 126827-25-6 is a valid CAS Registry Number.
