207989-89-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 207989-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,9,8 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 207989-89:
(8*2)+(7*0)+(6*7)+(5*9)+(4*8)+(3*9)+(2*8)+(1*9)=187
187 % 10 = 7
So 207989-89-7 is a valid CAS Registry Number.
