136992-56-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136992-56-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,9 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 136992-56:
(8*1)+(7*3)+(6*6)+(5*9)+(4*9)+(3*2)+(2*5)+(1*6)=168
168 % 10 = 8
So 136992-56-8 is a valid CAS Registry Number.
