1246357-05-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1246357-05-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,3,5 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1246357-05:
(9*1)+(8*2)+(7*4)+(6*6)+(5*3)+(4*5)+(3*7)+(2*0)+(1*5)=150
150 % 10 = 0
So 1246357-05-0 is a valid CAS Registry Number.
