1284214-22-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1284214-22-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,4,2,1 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1284214-22:
(9*1)+(8*2)+(7*8)+(6*4)+(5*2)+(4*1)+(3*4)+(2*2)+(1*2)=137
137 % 10 = 7
So 1284214-22-7 is a valid CAS Registry Number.
