156393-78-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156393-78-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,3,9 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 156393-78:
(8*1)+(7*5)+(6*6)+(5*3)+(4*9)+(3*3)+(2*7)+(1*8)=161
161 % 10 = 1
So 156393-78-1 is a valid CAS Registry Number.
