123214-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123214-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,2,1 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123214-40:
(8*1)+(7*2)+(6*3)+(5*2)+(4*1)+(3*4)+(2*4)+(1*0)=74
74 % 10 = 4
So 123214-40-4 is a valid CAS Registry Number.
