1357486-62-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1357486-62-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,7,4,8 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1357486-62:
(9*1)+(8*3)+(7*5)+(6*7)+(5*4)+(4*8)+(3*6)+(2*6)+(1*2)=194
194 % 10 = 4
So 1357486-62-4 is a valid CAS Registry Number.
