191594-81-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 191594-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,5,9 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 191594-81:
(8*1)+(7*9)+(6*1)+(5*5)+(4*9)+(3*4)+(2*8)+(1*1)=167
167 % 10 = 7
So 191594-81-7 is a valid CAS Registry Number.
