136749-69-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136749-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,4 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136749-69:
(8*1)+(7*3)+(6*6)+(5*7)+(4*4)+(3*9)+(2*6)+(1*9)=164
164 % 10 = 4
So 136749-69-4 is a valid CAS Registry Number.
