1234320-87-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1234320-87-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,3,2 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1234320-87:
(9*1)+(8*2)+(7*3)+(6*4)+(5*3)+(4*2)+(3*0)+(2*8)+(1*7)=116
116 % 10 = 6
So 1234320-87-6 is a valid CAS Registry Number.
