152241-69-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 152241-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,2,4 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 152241-69:
(8*1)+(7*5)+(6*2)+(5*2)+(4*4)+(3*1)+(2*6)+(1*9)=105
105 % 10 = 5
So 152241-69-5 is a valid CAS Registry Number.
