1213702-53-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1213702-53-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,3,7,0 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1213702-53:
(9*1)+(8*2)+(7*1)+(6*3)+(5*7)+(4*0)+(3*2)+(2*5)+(1*3)=104
104 % 10 = 4
So 1213702-53-4 is a valid CAS Registry Number.
