188710-33-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188710-33-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,7,1 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188710-33:
(8*1)+(7*8)+(6*8)+(5*7)+(4*1)+(3*0)+(2*3)+(1*3)=160
160 % 10 = 0
So 188710-33-0 is a valid CAS Registry Number.
