1188557-67-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1188557-67-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,8,5,5 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1188557-67:
(9*1)+(8*1)+(7*8)+(6*8)+(5*5)+(4*5)+(3*7)+(2*6)+(1*7)=206
206 % 10 = 6
So 1188557-67-6 is a valid CAS Registry Number.
