1383540-94-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1383540-94-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,3,5,4 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1383540-94:
(9*1)+(8*3)+(7*8)+(6*3)+(5*5)+(4*4)+(3*0)+(2*9)+(1*4)=170
170 % 10 = 0
So 1383540-94-0 is a valid CAS Registry Number.
