1217864-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1217864-53-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,8,6 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1217864-53:
(9*1)+(8*2)+(7*1)+(6*7)+(5*8)+(4*6)+(3*4)+(2*5)+(1*3)=163
163 % 10 = 3
So 1217864-53-3 is a valid CAS Registry Number.
