1392411-83-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1392411-83-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,2,4,1 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1392411-83:
(9*1)+(8*3)+(7*9)+(6*2)+(5*4)+(4*1)+(3*1)+(2*8)+(1*3)=154
154 % 10 = 4
So 1392411-83-4 is a valid CAS Registry Number.
