1338227-86-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1338227-86-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,2,2 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1338227-86:
(9*1)+(8*3)+(7*3)+(6*8)+(5*2)+(4*2)+(3*7)+(2*8)+(1*6)=163
163 % 10 = 3
So 1338227-86-3 is a valid CAS Registry Number.
