136138-48-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136138-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,1,3 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 136138-48:
(8*1)+(7*3)+(6*6)+(5*1)+(4*3)+(3*8)+(2*4)+(1*8)=122
122 % 10 = 2
So 136138-48-2 is a valid CAS Registry Number.
