109216-92-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109216-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,1 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109216-92:
(8*1)+(7*0)+(6*9)+(5*2)+(4*1)+(3*6)+(2*9)+(1*2)=114
114 % 10 = 4
So 109216-92-4 is a valid CAS Registry Number.
