152654-91-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 152654-91-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,6,5 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 152654-91:
(8*1)+(7*5)+(6*2)+(5*6)+(4*5)+(3*4)+(2*9)+(1*1)=136
136 % 10 = 6
So 152654-91-6 is a valid CAS Registry Number.
