136182-63-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136182-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,1,8 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136182-63:
(8*1)+(7*3)+(6*6)+(5*1)+(4*8)+(3*2)+(2*6)+(1*3)=123
123 % 10 = 3
So 136182-63-3 is a valid CAS Registry Number.
