158229-59-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158229-59-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,2,2 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 158229-59:
(8*1)+(7*5)+(6*8)+(5*2)+(4*2)+(3*9)+(2*5)+(1*9)=155
155 % 10 = 5
So 158229-59-5 is a valid CAS Registry Number.
