321870-36-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 321870-36-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,8,7 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 321870-36:
(8*3)+(7*2)+(6*1)+(5*8)+(4*7)+(3*0)+(2*3)+(1*6)=124
124 % 10 = 4
So 321870-36-4 is a valid CAS Registry Number.
