99136-67-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99136-67-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,3 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99136-67:
(7*9)+(6*9)+(5*1)+(4*3)+(3*6)+(2*6)+(1*7)=171
171 % 10 = 1
So 99136-67-1 is a valid CAS Registry Number.
