136558-59-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136558-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,5 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136558-59:
(8*1)+(7*3)+(6*6)+(5*5)+(4*5)+(3*8)+(2*5)+(1*9)=153
153 % 10 = 3
So 136558-59-3 is a valid CAS Registry Number.
