324012-37-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 324012-37-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,4,0,1 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 324012-37:
(8*3)+(7*2)+(6*4)+(5*0)+(4*1)+(3*2)+(2*3)+(1*7)=85
85 % 10 = 5
So 324012-37-5 is a valid CAS Registry Number.
