136506-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136506-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,0 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136506-77:
(8*1)+(7*3)+(6*6)+(5*5)+(4*0)+(3*6)+(2*7)+(1*7)=129
129 % 10 = 9
So 136506-77-9 is a valid CAS Registry Number.
