1133862-77-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1133862-77-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,3,8,6 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1133862-77:
(9*1)+(8*1)+(7*3)+(6*3)+(5*8)+(4*6)+(3*2)+(2*7)+(1*7)=147
147 % 10 = 7
So 1133862-77-7 is a valid CAS Registry Number.
