1370406-93-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1370406-93-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,0,4,0 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1370406-93:
(9*1)+(8*3)+(7*7)+(6*0)+(5*4)+(4*0)+(3*6)+(2*9)+(1*3)=141
141 % 10 = 1
So 1370406-93-1 is a valid CAS Registry Number.
